both animal and plant cells have ribosomes, cell membranes, nucleus, cytoplasm and mitochondria
only a plant cell has chloroplasts
only a plant cell has a cellulosecellwall
only a plant cell has a vacuole
the upper epidermis covers the surfaces and protects them and secrete a waxy substance that waterproofs the leaf
the palisade mesophyll contains chloroplasts for photosynthesis
the spongy mesophyll contains some chloroplasts and has big air spaces and a large surface area for easier diffusion of gases
the xylem transports water and minerals from the roots to the leaves
the phloem transport sugars from the leaves to the rest of the plant
the lower epidermis contains guard cells and stomata
the guard cells open and close the stomata
the stomata are pores to allow gas exchange in leaves
the meristem tissues are found at growing tips of roots and shoots, and between xylem/ phloem vessels, it contains rapidly dividing plant cells that grow and differentiate into all the other cell types needed
the palisade mesophyll tissue is composed of many specialised palisade cells that work together yo carry out photosynthesis, so it is a tissue
a leaf comprises of many different tissues (eg vascular tissue, phloem tissue, xylem tissue, palisade and spongy mesophyll tissue etc) that work together to carry out photosynthesis and so a leaf is considered an organ
mitosis takes place in meristem tissue
the leaves carry out photosynthesis
the stem supports the leaves and flowers and also transports
the roots absorb water and minerals from soil and also anchors the plant to the ground
