Plant Cells vs Animal Cells
Autor Rebecca Woodbury Ph. D.en Limba Engleză Paperback – 25 iun 2020
Both plant cells and animal cells are surrounded by a cell membrane and have organelles, which are structures inside cells that do different jobs. The nucleus of a cell is the organelle where DNA is made and held. DNA is a strand of linked atoms that tell the cell what to do. A ribosome is an organelle that makes proteins, which are long chains of atoms. Proteins do all the work inside a cell, cutting, joining, and moving molecules. A mitochondrion is an organelle that makes energy for the cell.
Plant and animal cells are also different. Plant cells have a stiff outer cell wall in addition to a cell membrane. Animals cells have only a cell membrane. Plant cells have chloroplasts, which are organelles that catch sunlight to make food. Animal cells do not have chloroplasts and do not make food from sunlight. Animals get their food from eating other animals and plants.
