C! Because animal cells don’t have a cell wall! Have fun in Science!
Answer:
B
Explanation:
To begin with, it is clear that this cell has a cell wall (the rigid cubicle like structure around the cell). Only plants (that can carry out photosynthesis) have a cell wall. Secondly, one can view the chloroplasts in the cell (the organelles with green pigments inside). This is where photosynthesis takes place in the cell.
Answer:
The answer is A) Phagocytosis.
Explanation:
An amoeba usually gets its nutrients from engulfing large food particles by the process of phagocytosis.
- As an amoeba approaches the desired food particle, it <u>extends it pseudopods</u> around it, eventually <em>surrounding the food </em>and internalizing it.
- The food then becomes enclosed by the pseudopodia, creating a <u>food vacuole</u>.
- Digestive enzymes, such as <u>lysosomes</u>, will <u>fuse with the food vacuole</u> and start breaking down the food. The nutrients will then be diffused throughout the cytoplasm.
