Producer/ Consumer Cell part that produces is a chloroplast. Cell part that controls what enters and leaves is a cell membrane. Cell part that contains DNA and controls cell nucleus. Cell part that breaks down food for energy mitochondria. The animal cell has a small one and the plant cell has a large vacuole.

4
Cell Membrane vs. Cell Wall Cell membrane is a protective flexible barrier that controls what enters and leaves the cell Cell wall is a rigid structure that surrounds the cell membrane and provides support to the cell
5
Flagella and Cilia Flagella- helps cell travel with whipping action Cilia- helps cell move with tiny hairs

Animal and Plant Cells Animal: Cell Membrane – Controls what enters and exits the cell Mitochondria – Converts glucose into energy for the cell Cytoplasm – gel like fluid that the organelle move in Vacuole – Holds water, nutrients, and waste Nucleus – controls the activities of the cell, where DNA can be found Plants: Cell wall: to provide structure and protection Chloroplasts: where photosynthesis occurs, contains chlorophyll

Photosynthesis Radiant energy is used to convert carbon dioxide and water into a chemical energy called glucose and a byproduct of oxygen. Carbon dioxide enters the plant via the stoma and travels to the chloroplast. Water enters the roots and travels to the chloroplast where the chemical bonds of both compounds are broken. Through the process of photosynthesis the atoms of hydrogen, oxygen, and carbon are then formed into a glucose compound. The left over oxygen is discarded from the plant through the stoma as a waste product. Only plants go through photosynthesis!
8
Photosynthesis Carbon dioxide plus water and radiant energy yield glucose and oxygen 6CO2 + 6H2O ==> C6H12O6 + 6O2. Reactants: Carbon dioxide, water, radiant energy Products: Glucose and oxygen
