Photosynthesis
The process by which organisms that have chloroplasts use light, energy, carbon dioxide, and water to make sugar.
When there is little water in the air what do Stomata usually do?
stomata usually close to conserve water.
What are the three microscope magnifications and what is the field of view size for each?
40x=4mm
100x=2mm
400x=.4mm
Cell Membrane
Cell boundary that controls what enters and leaves the cell
Cell Wall
A rigid layer that supports the cell and provides shape
Chloroplast
Converts sun’s energy into food (sugars)
Cytoplasm
Internal fluid that contains the cell structures
Endoplasmic Reticulum
A membranous structure that assembles proteins and parts of the cell membrane
Lysosome
Digests cellular waste
Mitochondrion
Converts the energy in food into usable energy for the cell
Nucleus
Contains the cell’s genetic material (DNA)
Ribosomes
Makes proteins
Vacuoles
Stores water and other substances

Stomata (stoma)-
Openings on the surface of leaves that allow gas exchange.
What do guard cells do?
Guard cells control the opening and closing of the stomata.
