Cell Biology Pre Test

The process where body cells are copied is called?

• Cellular respiration

• Photosynthesis

• Mitosis

• Meiosis

Which organelle of the cell contains DNA and genetic material?

• Chloroplasts

• Ribomsomes

• Cytoplasm

• Nucleus

According to the cell theory...

• All cells have cell walls

• Cells can arise spontaneously

• The cell is the basic unit of structure in organisms

• All cells have a nucleus

SB3:Why are there less air bubbles as the plant is place further away from the light source

• because cellular respiration decreases when there is less light
• because the light independent reaction decreases when there is less light
• because photosynthesis decreases as a plant is moved further away from a light source
• the wavelength increases as a plant is placed further away from a light source

Functions in energy production, known as the energy factory of the cell

• mitochondria
• chloroplast
• vacuole
• cytoplasm

Semi-permeable layer around the cell that encloses the contents of the cell

• nucleus
• cell membrane
• cell wall
• chloroplast

I am found in plant cells. I am rigid, strong & stiff. I give support to the plant cell.  I give the cell it's box shape

• cell membrane
• cell wall
• chlorophyll
• mitochondria

The major function of ribosomes is to

• Make fats
• Synthesize protein
• Digest protein
• Make sugars

What is the name of the process where particles move from a high concentration to a low concentration (down a concentration gradient)?

• Diffusion

• Osmosis

• Active Transport

What is osmosis?

• Movement of water from a concentrated solution to a dilute solution.

• Movement of water from a dilute solution to a concentrated solution.
