Photosynthesis

Photosynthesis occurs in plant and animal cells. True or False?

• True

• False

What is the purpose of photosynthesis?

• To produce ATP for life processes

• To produce 2 identical daughter cells

• To produce haploid gametes

• To produce glucose that can then be used in the process of respiration

How is water absorbed into the root cells for photosynthesis?

• Osmosis

• Diffusion

• Facilitated diffusion

• Exocytosis

What are the products of photosynthesis

• Carbon dioxide and Glucose

• Water and Carbon dioxide

• Water, Oxygen and Glucose

• Glucose, 36 ATP and Carbon dioxide

Which two of these statements are true for both chloroplasts and mitochondria

• They both have chlorophyll

• They both have a double membrane

• They are both found in plant cells

• They both have cristae

_______ are the site of photosynthesis. They are stacked into grana to increase SA:Vol ratio.

• Lamellae

• Stroma

• Chlorophyll

• Thylakoids

What is the function of the clear stroma in the chloroplast?

• Controls the transport of substances in and out of the organelle

• Allows light to reach the grana and contains enzymes for the process of photosynthesis

• Provides a large surface area to volume ratio for efficient transport of substances in and out of the chloroplast

• Contains chlorophyll for absorbing light energy

Where do the light-dependent reactions of photosynthesis take place?

• Inner Membrane

• Lamella

• Stroma

• Thylakoids

What adaptation does this plant have to help it tolerate the intense sunlight?

• Large range of light absorbing pigments

• Spongy mesophyll with lots of chloroplasts

• Smaller chloroplasts

• Larger chloroplasts

C on the diagram.

These are cells that are tightly packed together with large numbers of chloroplasts. What is C?

• Palisade cells

• Upper epidermis

• Cuticle

• Guard cells
