Q

What is the function of a cell wall?

A

The cell wall is made of cellulose and gives support and shape to all plant cells. The structure is strong and rigid which allows the cell to be supported as turgor pressure increases.

22
Q

List all three parts of the cell theory:

A

Cells are the most basic units of life, all cells come from preexisting cells, and all living organisms are made up of one or more cells

23
Q

The turning of all or part of a plant (and other organisms) in response to the direction of light.

A

Phototropism

24
Q

The turning of all or part of a plant (and other organisms) in response to the sensation or downward pull of gravity.

A

Geotropism/Gravitropism

25
Q

What is thigmotropism?

A

The turning of all or part of a plant (and other organisms) in response to touch

26
Q

Define turgor pressure

A

The amount of pressure the vacuole puts on the cell membrane and cell wall

27
Q

Which type of cell(s) contain the organelle called a vacuole?

A

Plant and animal cells

28
Q

Which type of cell is larger, more complex, and generally rounder in shape? Eukaryotic or prokaryotic

A

Eukaryotic

29
Q

What is the function of a vacuole?

A

To store food, water, and waste

30
Q

What is the function of chloroplast?

A

To store chlorophyll, which absorbs and traps energy from the sun. This process is called photosynthesis

31
Q

What is cytoplasm

A

Cytoplasm is the gel-like fluid that fills the inside of ALL types of cells. It is the fluid that all parts of cells float in.

32
Q

Which type of cells contain ribosomes? Plant, Animal, Prokaryotic?

A

Ribosomes are in all types of cells.

33
Q

What part of the cell surrounds the entire cell (like an outer skin) and controls what comes in and out of the cell?

A

The cell membrane

34
Q

What is the mitochondria

A

Mitochondria is the “power house” organelle of cells. It converts food into energy (ATP).
