Answer 3

Ribosomes

Question 4

Has ribosomes on its surface and is involved in protein synthesis and transport.

Answer 4

Rough Endoplasmic Reticulum

Question 5

Lacks ribosomes and is involved in lipid synthesis, detoxification, and calcium storage.

Answer 5

Smooth Endoplasmic Reticulum

Question 6

Modifies, sorts, and packages proteins and lipids for storage or transport out of the cell.

Question 10

Regulates what enters and exits the cell and provides protection and structure. It is selectively permeable.

Answer 10

Plasma Membrane (Cell Membrane)

Question 11

Conducts photosynthesis by converting solar energy into chemical energy (glucose). (Plant cells)

Question 12

Stores nutrients, waste products, and helps maintain turgor pressure in plant cells. In animal cells, ________ are smaller and involved in waste removal.

Answer 12

Vacuoles

Question 13

Helps with cell division by organizing the mitotic spindle and ensuring proper chromosome separation. (In animal cells)

Answer 13

Centrioles

Question 14

The jelly-like substance that fills the cell, where most cellular activities occur, including chemical reactions.

Answer 14

Cytoplasm

Question 15

Provides additional support and protection, and helps maintain the shape of the plant cell. (plant cell)

Answer 15

Cell Wall

Question 16

Lacks a true nucleus. DNA is found in a region called the nucleoid, not enclosed by a membrane.
