Cell Processes Review (13.5 Week Checkpoint)

Cell Processes Review (13.5 Week Checkpoint)

Photosynthesis:

• 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

• Occurs in plants; makes food

• Needs 3 things from the environment: Carbon Dioxide (CO₂ ), Water (H₂O) and Sunlight. These are REACTANTS.

• Products of Photosynthesis are: glucose (sugar): C₆H₁₂O₆ and Oxygen: 6O₂

Multiple Choice

Ms. Clark's classroom at her old school didn't have windows. She was given a plant that she watered daily. The plant ended up dying. What key environmental factor was missing and helped cause the plant to die?

• oxygen

• glucose

• nucleus

• sunlight

Multiple Choice

What are the products of Photosynthesis?

• carbon dioxide and glucose

• carbon dioxide and sunlight

• glucose and oxygen

• water and sunlight

Multiple Choice

In what way are photosynthesis and respiration related to each other?

• The reactants of photosynthesis are the reactants of respiration.

• The products of photosynthesis are the products of respiration.

• The products of photosynthesis are the reactants of respiration.

• There is no relation.

Multiple Choice

When plants undergo photosynthesis, they are using sunlight to make glucose (sugar). What type of energy transformation does this match?

• mechanical energy>>> sound energy

• light/radiant energy>>> chemical energy

• nuclear energy>>>sound energy

• sound energy>>>nuclear energy

Cell Cycle: has 3 parts

• Part 1: Interphase

• Part 2: Mitosis: prophase, metaphase, anaphase, telophase

• Part 3: Cytokinesis

• There are 3 reasons why body cells reproduce: 1) growth 2) repair 3) replacement

Multiple Choice

Which of the 3 stages of the cell cycle does this picture represent?

• mitosis

• interphase

• cytokinesis

Multiple Choice

• interphase

• cytokinesis

• mitosis

Multiple Choice

Which of the 3 stages of the cell cycle does this picture represent?

• mitosis

• interphase

• cytokinesis

Multiple Choice

Ms. Clark's nephew has grown so much that he is now the tallest member of her family. He has to lean over to give her a hug. What process explains his growth?

• diffusion

• photosynthesis

• osmosis

• mitosis

Multiple Choice

Chromosomes line up in the middle of the cell. What stage of mitosis does this describe?

• anaphase

• telophase

• prophase

• metaphase

Diffusion and Osmosis

• Diffusion: movement of particles from HIGHER concentration to LOWER concentration

• Osmosis: special kind of diffusion; the movement of WATER from HIGHER concentration to LOWER concentration

Multiple Choice

During osmosis...

• water moves from high to low concentration

• large or oddly shaped molecules move across a cell membrane

• water moves when energy is used

• proteins are built
