Answer 9

Is the cell structure responsible for homeostasis.

Question 10

What is the selective permeability?

Answer 10

The ability of the PM to allow substances to pass through and to keep others out.

Question 11

What is the cytoplasm?

Answer 11

Is the semifluid environment inside the cell.

It provides an anchor for the organelles using very thin fibers called microfilaments and microtubules, what is it?

Answer 12

Cytoskeleton

Question 13

What is the nucleus and what does it contain?

Answer 13

Like the “manager” of the cell, it contains DNA

The place where proteins and lipids are made.

Question 18

How is the ER divided?

Answer 18

Into the Rough ER and the Smooth ER

Question 19

What is the Rough ER?

Answer 19

Where ribosomes are attached.

Vacuoles

Question 25

Are vesicles that carry substances which digest old or excess organelles.

Answer 25

Lysosomes

Are structures connected to the outside of the PM in some prokaryotic and Eukaryotic cells.

Answer 28

Cilia and Flagella

Question 29

What is cilia?

Answer 29

Are short, Look like hairs, Move in a “rowing” motion, Many per cell

Question 30

Clorophyll
