Did you know?
WebFunction of Phloem Phloem is the vascular tissue in charge of transport and distribution of the organic nutrients. From the leaves where they are produced by photosynthesis to the rest of the plant. The sugars are moved from the source, usually the leaves, to the phloem through active transport.
WebThe three types of plant cells are found in each of the major types of plant tissues: dermal, ground, and vascular tissues. Dermal tissue covers the outside of a plant in a single layer of cells called the epidermis. It mediates most of the interactions between a plant and its environment. Ground tissue makes up most of the interior of a plant. WebPhloem consists of living cells. The cells that make up the phloem are adapted to their function: Sieve tubes - specialised for transport and have no nuclei. Each sieve tube has a …
