7th Grade Life Science: S7L2 Review

• M is Chloroplast, and O is a mitochondria

• M is a mitochondria, and O is a chloroplast

• M is the cytoplasm, and o is the nucleus

• M is the nucleus, and O is the cytoplasm

A student is developing a plant cell model. The mode dissolves. Which statement best evaluates this lysosome model?

• It is useful because it models that lysosomes break down materials/substances that enter them

• It is useful because it models that lysosomes dissolve solids without chemically changing them

• It is useful because it models that lysosomes contain a fluid while also having an opening allowing the fluid to spread into the cell.

• It is useful because it models that lysosomes are structured as fluid-filled cylinders

A student wants to develop a model of a plant cell and model many common characteristics. Plants and animal cells are eukaroyotic and share many common characteristics. Which list Best describes the characterstics for both models?

• a nucleus, cytoplasm, lysosomes, and cell wall that strengths the cell.

• a nucleus, cytoplasm, organelles, and cell membrane that controls the movement of substances into and out of the cell.

• a nucleus, cytoplasm, mitochondria, and a permanent vacuole that can hold large amount of water.

• a nucleus, cytoplasm, chloroplast that abosorbs energy

If the chloroplast in the plant stopped working, what will most likely happen to the cell?

• The ability to make food will be lost

• The ability to reproduce would decrease

• Anything would be allowed in the cell

• production assembly line

• Power line

• Control Room

• storage room

• Respiration, where carbon dioxide and oxygen at Q and R are taken in and then converted into thermal energy at S and T

• Photosynthesis where carbon dioxide and sunlight at Q&R are taken in and then converted into glucose and oxygen at S and T

• photosynthesis are taken in and then converted into water vapor and thermal energy at S &T

• The red blood cell will absorb water and increase in size

• The red blood cell will first absorb water, then lose water

• The red blood cell will lose water and decrease in size

• The red blood cell will first lose water, the absorb it.
