Cells are the building blocks of all living things. Your garden plants are no exception.
All animal and plant cells both contain the following:
Differences between plant and animal cells
Animal cells are generally rounded and irregular, while plant cells tend to be rectangular and more rigid. This rigidity comes from cellulose, pectin, hemicellulose, and occasionally lignin. This is also what holds your garden plants upright. When they are suffering water stress, they lose some of that rigidity and start to wilt.
Plant cells are also different from animal cells because they have cell walls and an organelle called a chloroplast. Animal cells do not have chloroplasts because they do not produce their own food. If we had chloroplasts, we would probably be green! Chloroplasts contain the chlorophyll used in photosynthesis.
You can grow a surprising amount of food in your own yard. Ask me how!
