1. animal cells do not have a cell wall and have an irregular shape, plant cells have a cell wall and are regular in shape. 2. animal cells do not have a chloroplast. 3. animal cells have a small temporary vacuoles or no vacuole while plant cells have large vacuoles located in the center of the cell. 4. animal cell- nucleus is usually centrally located, plant cell- due to center location of vacuole nucleus may be located on the edge of the cell
nutrition: ingest and digest small organisms through vesicles, growth: nutrients from digestion are used to provide energy and materials for growth, excretion: waste products from metabolism are expelled through diffusion, response: paramecium moves toward or away from external stimuli therefore responding to environment, metabolism: contains enzymes in cytoplasm that catalyze the metabolic reactions, reproduction: asexual and sexual, homeostasis: fill up with water and remove this water maintaining balance
nutrition: chloroplast produces food through photosynthesis, growth: grows through absorption of materials and photosynthesis,excretion: expelled through diffusion, response: eyespot that can detect the brightest light moves toward light stimuli and is able to respond to environment, metabolism: contains enzymes that catalyze metabolic reactions, homeostasis: vacuoles fill up with water and expel this water
1. all living organisms come from cells. 2. the cell is the basic unit of structure and organization in organisms. 3. cells come from preexisting cellscell theory
