The cell membrane forms a protective barrier between the external and internal environments. It is referred to as _____________, because it allows some substances to cross more easily than others and blocks other substances from crossing into the cell.
A. Impermeable
B. A fluid mosaic
C. A plasma membrane
D. Selectively permeable
D. Selectively permeable
the process by which plants, algae, and some bacteria use sunlight, carbon dioxide, and water to make food
Photosynthesis
the process by which cells use oxygen to produce energy from food
Cellular Respiration
An analysis of a plant cell would show which ability that an animal cell would lack? What organelle would be involved in this process?
A. The plant cell can perform protein production, which occurs in the nucleus
B. The plant cell can perform cellular respiration, which occurs in the cell wall
C. The plant cell can produce glucose from light energy, which occurs in the chloroplast
D. The plant cell can perform cell division, which occurs when the nucleus an the cell membrane divide
C. The plant cell can produce glucose from light energy, which occurs in the chloroplast
Your eyes are made up of many different parts. Each part has a special job in helping you to see. How would you describe the cells that make up the parts of your eye?
A. Each part of the eye is made up of identical cells
B. The parts of the eye are made of the same cells that make up our skin
C. Each part of the eye is made of special cells that help with a certain job
D. The eye is not made up of cells. Instead it is made of tissues and each tissue has a special job
C. Each part of the eye is amde of special cells that help with a certain job
All cells must allow certain molecules, like water, nutrients, and minerals, to pass through the outer layer of the cell. Which organelle acts as a semipermeable barrier between the cell and the environment?
Cell Membrane
the movement of particles from regions of higher density to areas of lower density
diffusion
a barrier that allows all types of substances, like water and nutrients, to pass through it freely
Permeable Membrane

A. The chloroplast controls division of the cell
B. The chloroplast provides structue to the cell
C. The chloroplast manufactures proteins for the cell
D. The chloroplast is where photosynthesis occurs
D. The chloroplast is where photosynthesis occurs
Select all of the organs from those listed.
Blood, Brain, Eye, Leukocyte, Muscle

The human stomach is an organ that helps us digest food. The stomach is one of many organs involved in the process of digestion. Others include the esophagus, small intestine, pancreas, and gall bladder. What name is given to a set of organs that work together to perform a specific function?
Organ System
a special barier in a cell that acts like a selective bouncer, allowing some substances, like water and small nutrients, to pass through while blocking others, such as large molecules to maintain the cell's balance
Semi-Permeable Membrane
diffusion of water through a semipermeable membrane
Osmosis
Explain how animals depend on photosynthesis to survive.
