13 Cells have a nucleus. Surrounding the nucleus is the nuclear membrane Cells have a nucleus. Surrounding the nucleus is the nuclear membrane. Inside the nucleus are the chromosomes (DNA, genes). The chromosomes control the rest of the cell and pass on characteristics to the offspring.
21 The lysosomes contain digestive enzymes that break down worn-out cell parts, food that the cell has taken in, or invaders like bacteria.
22 Lysosome Cell membrane Cytoplasm DNA Nucleus Ribosomes Golgi body Endoplasmicreticulum
23 Vacuoles hold stuff for the cell Vacuoles hold stuff for the cell. They can hold water, food, or anything that the cell takes in.

25 The mitochondria get the food that has already been broken into small pieces by the lysosomes. The mitochondria break all the rest of the bonds.
26 Remember, when a bond is broken, energy is released Remember, when a bond is broken, energy is released. The mitochondria are called the “Powerhouses” of the cell because they give the cell its energy.
34 Plant cells are rectangular Plant cells are rectangular. When you look at plant cells under a microscope, they look like a brick wall.
35 Plant cells have a cell wall which surrounds the cell membrane Plant cells have a cell wall which surrounds the cell membrane. They also have chloroplasts which give the plant its green color and lets the plant make food.
36 Chloroplasts trap light energy and put it into bonds Chloroplasts trap light energy and put it into bonds. That is how energy gets into our food.
