True. Spongy mesophyll cells are found in the leaf tissue of plants and are involved in the exchange of gases necessary for photosynthesis.
Animals are eukaryotic organisms, meaning their cells contain a defined nucleus enclosed by a membrane. Prokaryotes, on the other hand, lack a nucleus and membrane-bound organelles in their cells.
True. Subtropical desert climates are commonly found in areas dominated by subtropical high-pressure cells, which create dry conditions and inhibit cloud formation and precipitation. Examples include the Sahara Desert and Arabian Desert.
False. A northerly wind comes from the north and moves towards the south.
False. Earth is actually closest to the sun during the month of January.
they are prokaryotic
False. Eukaryotic cells generally contain more DNA than prokaryotic cells. Eukaryotic cells have their DNA enclosed within a nucleus, whereas prokaryotic cells have their DNA located in the cytoplasm.
Prokaryotic cells do NOT have a nucleus.
Prokaryotic cells are simple cells without a true nucleus or membrane-bound organelles, found in bacteria and archaea. Eukaryotic cells are complex cells with a true nucleus and membrane-bound organelles, found in plants, animals, fungi, and protists. Eukaryotic cells are generally larger and more structurally complex compared to prokaryotic cells.
hoe do you not get it?? the answer is obvious its true the other person has no prove and are trying to get u to fail ur science test trust me its true and u can search it up IM TRYING TO HELP U TRUST MEEE ;)
Not all cells have true organelles. prokaryotic cells (bacteria, for example) have no true nucleus and have ribosomes, which are not membrane-bound. eukaryotic cells do have true organelles. they make up the world of life you can see (plants, animals, most fungi)
Prokaryotic cells do NOT have a nucleus.
Prokaryotic cells do not have a membrane-bound nucleus or other membrane-bound organelles, while eukaryotic cells have a true nucleus bound by a nuclear membrane and contain membrane-bound organelles. Prokaryotic cells are generally smaller and simpler in structure compared to eukaryotic cells. Examples of prokaryotic cells include bacteria and archaea, while examples of eukaryotic cells include plants, animals, fungi, and protists.
Fungi cells are eukaryotic because they have true nuclei with a nuclear membrane, as well as other membrane-bound organelles like mitochondria and Golgi apparatus. Prokaryotic cells, such as bacteria, lack these features and have a simpler cellular structure.
True. The ancestor of all eukaryotic cells is thought to have evolved approximately 2 billion years ago through a process of endosymbiosis, where prokaryotic cells engulfed other prokaryotic cells, leading to the formation of more complex eukaryotic cells.
Eukaryotic cells have a true nucleus that encloses genetic material while prokaryotic cells do not have a nucleus. Eukaryotic cells are typically larger and more complex than prokaryotic cells, containing organelles such as mitochondria and the endoplasmic reticulum. Eukaryotic cells are found in plants, animals, fungi, and protists, while prokaryotic cells are found in bacteria and archaea.
Eukaryotic cells have a nucleus and prokaryotic cells have no true nucleus.
