What is gametangium?
A gametangium is a structure in fungi, algae, and some plants that produces and encloses gametes for sexual reproduction. It can contain male gametes (sperm) or female gametes (eggs) or both. Gametangia are often specialized structures that allow for the fusion of gametes to create a zygote.
Does a cell contain mitochondria?
Not all cells contain mitochondria. Mitochondria are found in most eukaryotic cells, which are cells that have a nucleus and other organelles. Mitochondria are often referred to as the powerhouse of the cell because they generate most of the cell's energy through a process called cellular respiration.
What is in the center of every cell?
The nucleus is typically found in the center of animal cells, containing the cell's genetic material. Plant cells often have a large central vacuole in the center, surrounded by the nucleus and other organelles.
How does pus cells look like?
The cells that contribute to pus are both dead tissue cells from where the infection is at as well as dead inflammatory cells, usually neutrophils. Microscopically, these cells appear destroyed, often with disrupted cellular architecture and hypereosinophilic cytoplasm. The basophilic nucleus is often faded or absent as well.
What cell do all eukaryote cells contain?
Living cells have cell membranes, genetic material & ribosomes in COMMON. 1. Eukaryotes have membrane bound organelles. 2. They are much larger to hold these organelles. 3. They have more than one chromosome 4. Often are multicellular 5. Have peroxisomes and lysomes 6. Have mitochondria 7. Larger ribosomes

What major difernce between prokayote and eukAyote cells?
One major difference is that prokaryotic cells lack membrane-bound organelles such as a nucleus, while eukaryotic cells have a nucleus and other membrane-bound organelles. Prokaryotic cells are generally smaller and simpler in structure compared to eukaryotic cells. Additionally, eukaryotic cells undergo mitosis for cell division, while prokaryotic cells often undergo binary fission.
Does a cell contain mitochondria?
Not all cells contain mitochondria. Mitochondria are found in most eukaryotic cells, which are cells that have a nucleus and other organelles. Mitochondria are often referred to as the powerhouse of the cell because they generate most of the cell's energy through a process called cellular respiration.
What is the name of the large often central organelle in eukaryotic cells that contains chromosomes?
The organelle is called the nucleus. It serves as the control center of the cell, housing the genetic material in the form of chromosomes, which contain DNA. The nucleus plays a vital role in gene expression, cell division, and overall cellular function.
Is a wasp a eukaryote?
Yes, wasps are eukaryotes because they have cells with a true nucleus enclosed by a membrane, and other membrane-bound organelles within their cells. Eukaryotes include all organisms with a complex cellular structure, such as animals, plants, fungi, and protists.
Is more than one nucleolus present in a cell?
Typically, a cell contains only one nucleolus. However, under certain conditions such as rapid cell growth or stress, some cells may contain multiple nucleoli.
How does a prokaryotic cell differ from eukaryotic cells?
It has a nuclear membrane
Do all cells have brains?
No. The nucleus is often compared to the brain, but it is not really a brain made of brain tissue.
What are band white blood cells?
"band" in this case, refers to the form of the nucleus. The nucleus of a "ripe" white cell is segmented where as in a band, the nucleus looks that way, ergo NOT segmented. Therefore, a band is a younger cell. In for instance, infections where the body needs more white cells, band white cells are seen more often.
What is in the center of every cell?
The nucleus is typically found in the center of animal cells, containing the cell's genetic material. Plant cells often have a large central vacuole in the center, surrounded by the nucleus and other organelles.

Microscopically, these cells appear destroyed, often with disrupted cellular architecture and hypereosinophilic cytoplasm. The basophilic nucleus is often faded or absent as well.
What do eurkaryotic cells have that prokaryotic cells do not?
Eukaryotic cells have a true nucleus containing their DNA, membrane-bound organelles such as mitochondria and endoplasmic reticulum, and are generally larger and more complex than prokaryotic cells. Prokaryotic cells lack a nucleus and membrane-bound organelles, and their DNA is typically found in a region called the nucleoid.
