When a unicellular organism such as a paramecium takes in food the food is contained in which organelle?
food vacuoles
Unicellular organisms include bacteria, protists, and yeast. For example, a paramecium is a slipper-shaped, unicellular organism found in pond water. It takes in food from the water and digests it in organelles known as food vacuoles.
What differences are there between a prokaryotic and eukaryotic cell?
Comparing prokaryotes and eukaryotes The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information.
Which organelle is responsible for the rough appearance of endoplasmic reticulum?
Proteins are assembled at organelles called ribosomes. When proteins are destined to be part of the cell membrane or exported from the cell, the ribosomes assembling them attach to the endoplasmic reticulum, giving it a rough appearance.
Which part of the plant cell is responsible for controlling the activities of other parts of the cell?
Terms in this set (10) Which part of a plant cell is responsible for controlling the activities of the other parts of the cell? Nucleus.
Is the rough ER in plant and animal cells?
There are two types of endoplasmic reticulum: rough endoplasmic reticulum (rough ER) and smooth endoplasmic reticulum (smooth ER). Both types are present in plant and animal cells. The two types of ER often appear as if separate, but they are sub-compartments of the same organelle.
How do the rough ER and ribosomes work together?
Rough ER is a host for ribosomes that continually attach to and detach from the ER surface. Essentially, the endoplasmic reticulum and ribosomes work together in order to synthesize proteins and have them transported to their final destination.
What in an animal cell controls what goes in and out?
Animal cells and plant cells
| Part | Function |
|---|---|
| Cell membrane | Controls the movement of substances into and out of the cell |
| Cytoplasm | Jelly-like substance, where chemical reactions happen |
| Nucleus | Carries genetic information and controls what happens inside the cell |
| Mitochondria | Where most respiration reactions happen |
Which part controls the activities of the animal cell?
The nucleus
The nucleus is the largest organelle within animal cells. The nucleus controls cell activity. It also contains the cell’s chromosomes.
