botany

• meristematic tissues are mass of young, immature and undifferentiated cells
• lateral meristems produce secondary growth in stems and roots
• apical meristems produce new parts at the tips of roots and shoots
• vascular tissue is made up of xylem and phloem
• types of meristematics are euromeristems and psudomeristems
• eumeristems formed from pre formed meristems; always keeps dividing and never loses its power of division
• pseudomeristems formed from differentiation of permanent tissues like cambium and cork cambium
• permanent tissues includes epidermis and periderm
• epidermis are outermost, protoderm derived layer of cells
• periderm are outer covering that replaces the epiderm of certain plants
• vascular tissues are arrangement of multiple cell types in vascular plants which allows for the transport of water and mineral ions
• two types of vasucular tissues are xylem and phloem
• xylem is a specialized type which transports water and nutrientsd
• phloem are responsible in transporting organic food materials
• root is a part of the plant which attaches it to the ground or to a support - conveying water and nourishment to the rest of the plant
• stem is the main body or stalk of a plant or shrub, occasionally subterranean
• leaf are flattened structure of a higher plant
• flower are seed-bearing plant that consists reproductive organs (stamens and carpels)
• fruit are fleshy products of a tree that contains seed and can be eaten as food
• the structure of a parenchyma are cube-shaped, loosely packaged, thin walled, relatively unspecialized and contains chloroplast
• parenchyma functions are photosynthesis, cellular respiration, storage
• collenchyma has thicker walls than parenchyma cells but thinner than sclerenchyma cells
• collenchyma function is support
• the structure of collenchyma is elongated, irregularly thickened walls
• sclerenchyma structure are very thick cell walls that contains lignin
• sclerenchyma functions are for mechanical strength, support
• botany is the branch of biology that deals with the study of plants, including structure, properties, and biochemical processes
