Cells

Question 1

Nucleolus

Answer 1

Concentration of RNA found in Nucleus, as well as chromatin and proteins.
Produces rRNA, subunits of ribosomes.

Question 2

Nuclear Envelope

Answer 2

Double membrane around nucleus, has nuclear pores

Controls what enters and leaves nucleus

Question 3

Rough ER

Answer 3

Membranous channels studded with ribosomes, makes proteins for export.

Question 4

Smooth ER

Answer 4

Membranous channels that make lipids, also detoxify poisons and toxins

Question 5

Golgi Apparatus

Answer 5

Flattened membrane saccules that process, package, and distribute products of ER

Question 6

Mitochondria

Answer 6

Double membrane organelle with inner folds called cristae. Where cellular respiration happens to make ATP, has inner fluid calle the matrix which contains DNA and ribosomes.

Question 7

Ribosomes

Answer 7

Consists of two RNA subunits that make proteins for the cell.

Question 8

Cytoplasm

Answer 8

Fluid that all cell organelles float in.

Question 9

Cytoskeleton

Answer 9

Consists of actin and intermediate filaments, and microtubules that provide support and structure for cell, also movement.

Question 10

Lysosomes

Answer 10

Membrane sacs containing enzymes that breakdown materials in the cell.

Question 11

Vacuoles

Answer 11

Stores fluids and other materials

Question 12

Vesicles

Answer 12

Membrane sac that stores and transports materials

Question 13

Cell membrane

Answer 13

Phospholipid bilateral that controls what enters and leaves the cell.

Question 14

Cell wall

Answer 14

Only in plants, provides shape an support, surrounds membrane

Question 15

Chloroplast

Answer 15

Contains chlorophyll, site of photosynthesis.

Question 16

Nucleus

Answer 16

Contains DNA of the cell, which controls the structure and function of the cell. The DNA is stored and packaged as chromatin.
