Question

1 multiple choice 1 point what is the primary function of the cell membrane? storing genetic information regulating the movement of substances in and out of the cell synthesizing atp packaging and modifying proteins 2 multiple choice 1 point who is credited with discovering cells? charles darwin robert hooke louis pasteur gregor mendel 3 multiple choice 1 point which organelle is responsible for photosynthesis in plant cells? mitochondria peroxisome nucleus chloroplast

Explanation:

1. The cell membrane is a semi - permeable barrier. Its main job is to control what enters and exits the cell. Genetic information is stored in DNA in the nucleus, ATP synthesis mainly occurs in mitochondria, and protein packaging/modification is done by the Golgi apparatus.
2. Robert Hooke first observed and named cells in 1665 when he looked at a thin slice of cork under a microscope. Darwin is known for evolution, Pasteur for microbiology and germ theory, and Mendel for genetics.
3. Chloroplasts contain chlorophyll which can capture light energy and convert carbon dioxide and water into glucose and oxygen during photosynthesis. Mitochondria are for cellular respiration, peroxisomes deal with metabolic reactions and breaking down hydrogen peroxide, and the nucleus contains genetic material.

Answer:

1. B. Regulating the movement of substances in and out of the cell
2. B. Robert Hooke
3. D. Chloroplast
