Irish B. Simeon August 07, 2009 11-St. Luke Mrs. Emilia Calma 1) Are cells alive? Why do you think this? Answer: Yes, cells are alive because they grow and multiply. And also cell is the basic unit of life.2) Where are cells located in your body? Answer: The cells are located in different parts of the body. 3) Where do the cells in your body get energy? Answer: They can get energy from the food we eat, they get nutrients and proteins. 4) How do your cells know what to do? What directs their functioning? Answer: Each cell has a control center called a nucleus. The nucleus contains the information that tells the cell what to do and when to grow and divide. This information is contained in genes, which are the building blocks of chromosomes. 7)How are plant cells different from animal cells? In what ways are they similar?Answer: Plants have a cell wall and membrane while animals have a cell membrane but haven't cell wall. Their similarities except for RBCs, both animal and plant cells have a nucleus. Both have the same organelles, floating in the cytoplasm i.e. the organelles are the mitochondria, Golgi body, ribosome, and the endoplasmic reticulum. 8) Does cellular respiration occur in plant cells? Answer: I believe Cellular respiration only occurs in plant cells. 9) What are the membranes in cells made of? Answer: It is a semi permeable lipid bilayer found in all cells.[2] It contains a wide variety of biological molecules, primarily proteins and lipids, which are involved in a vast array of cellular processes such as cell adhesion, ion channel conductance and cell signaling. The plasma membrane also serves as the attachment point for both the intracellular cytoskeleton and, if present, the extra cellular cell wall. 11) The cell membrane is selectively permeable, allowing only certain substances from the outside environment to enter the cell. What sorts of molecules pass through a phospholipids membrane easily? What sorts of substances do not pass through a membrane readily? Answer:Water can easily to the phospholipids membrane. While lipids, and ribosome cannot pass through the phospholipids membrane. nucleus mitochondrion cell membrane ribosomerough endoplasmic reticulum (rough ER) Cell membrane

Cell membrane
Part of a cell enclosed by cell membrane is called the protoplast. It includes cell organelles like cell membrane, cytoplasm, vacuole, cell nucleus etc. In the cytoplasm are found mitochondria, plastids, golgi bodies etc.
The nucleus and nucleolus both are membrane bound and important to the cell

What are the 2 main parts of the cell membrane?
The two main parts of the cell membrane are phospholipid bilayer and membrane proteins. The phospholipid bilayer forms the basic structure of the membrane, while membrane proteins are embedded within or attached to the bilayer, playing crucial roles in cell communication and transport.
What are the different parts that make up the cell?
The main parts of a cell include the cell membrane, cytoplasm, nucleus, and organelles such as mitochondria, endoplasmic reticulum, Golgi apparatus, and ribosomes. These components work together to carry out various functions necessary for the cell's survival and operation.
Which two organic molecules make up the cell membrane?
Phospholipids and cholesterol are the two main organic molecules that make up the cell membrane. Phospholipids form a lipid bilayer that provides structural integrity, while cholesterol helps maintain the fluidity and stability of the membrane.
What molecule makes up the bulk of a cell's membrane?
Phospholipids make up the bulk of a cell's membrane. They have a hydrophilic (water-attracting) head and two hydrophobic (water-repelling) tails, which form a lipid bilayer that provides the structure and integrity of the cell membrane.
If you are looking at a cell what are 2 things you would see in it that would make you know it was a eukaryotic cell?
There are two things that would make a person know a Eukaryota cell. The two things would be membrane bound nucleus and genetic material.
Name two parts of an animal cell that helps defend against invading substances?
the cell membrane and the lysosmes
Which are the two parts of mitocharda?
The two main parts of a mitochondrion are the outer membrane and the inner membrane. The inner membrane is where the electron transport chain and ATP synthesis occur, while the outer membrane helps separate the contents of the mitochondrion from the rest of the cell.
What are the 2 main parts of the cell membrane?
The two main parts of the cell membrane are phospholipid bilayer and membrane proteins. The phospholipid bilayer forms the basic structure of the membrane, while membrane proteins are embedded within or attached to the bilayer, playing crucial roles in cell communication and transport.
What is a cell membrane of?
There are multiple membranes in a cell. Two of them are the cell membrane and the nucleur membrane.
What two things make up a cell membrane?
phospholipids and embedded
What two things make up all cell membrane?

What 2 thing make up the cell membrane?
The cell membrane is primarily composed of lipids (such as phospholipids) and proteins. These two components work together to control the passage of substances in and out of the cell, maintain cell structure, and facilitate cell communication.
Substances that form parts of a cell membrane and many cell organelles are what?
They are of two types. The components that assemble to form the Cell [bi-lipid-layer] membrane are called fatty-acids, and the mostly proteinaceous Adjuncts,/ Ancillary Components are known as Cell Membrane Control Factors.
What are the two major types of active transports?
The two major parts of active transport are endocytosis and exocytosis. Endocytosis is taking material into the cell by means of infoldings in the cell membrane. There are two types of endocytosis: phagocytosis (large molecules) and pinocytosis (small molecules). Exocytosis is the release of materials from a cell. The vacuole membrane and the cell membrane fuse together and the contents are released.

Two major parts of a cell?
Cell have two main parts PROTOPLASM: The living part which is again divided into two i.e. Nucleus and cytoplasm NON PROTOPLASM: Non living part of the cell which contain vacuole and ergastic substances.
What are 3 basic parts of a cell?
The three basic parts of a cell are the cell membrane, which encloses the cell and regulates what enters and exits; the cytoplasm, a jelly-like substance that fills the cell and holds the organelles; and the nucleus, which contains the cell's genetic material.
