Each component of a cell has its own function. Animal and plant cells differ and they have similarities. Nucleus, cell membrane, cytoplasm and mitochondria are four cell components that are found ...

Plant cells have several structures not found in other eukaryotes. In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls ...

Plant cells don't produce glycogen but instead make different glucose polymers known as starches, which they store in granules. In addition, both plant and animal cells store energy by shunting ...

They therefore support the plant. Dissolved sugars and amino acids can be transported both up and down the stem. Companion cells, adjacent to the sieve tubes provide energy required to transport ...
