Question

1. which organelle is not found in a plant cell? *

chloroplast
mitochondria
ribosome
centriole

1. the diagram below represents two cells viewed using the same

magnification with the same microscope.
one possible conclusion that can be drawn about the activity of these two cells is
that:
mitochondria
cell a
cell b
a. more active transport occurs in cell b than in cell a.
b. more active transport occurs in cell a than in cell b.
c. cell b uses some of the extra mitochondria to make food.
d. cell a is a plant cell since it has a cell wall.

Explanation:

Question 23

Chloroplasts are for photosynthesis in plants. Mitochondria are for energy - production (present in plant cells). Ribosomes are for protein synthesis (present in plant cells). Centrioles are mainly in animal cells (help in cell division), not in most plant cells.

Mitochondria produce ATP (energy). Active transport requires energy. Cell A has more mitochondria, so more active transport (needs more energy) occurs in Cell A. Chloroplasts (not mitochondria) make food. No cell wall shown (so can't say Cell A is plant).

Answer:

centriole
