Cells of this tissue are living and show angular wall thickning. They also provide mechanical support. The tissue isA. xylemB. sclerechymaC. collenchymaD. epidermis |
|
Answer» Correct Answer - C Collenchyma This tissue provide mechanical support mainly to herbaceous young growing stem. The cells have angular thickening at the corners. Whereas, xylem is conductive complex tissue, transports water mineral Sclerenchyma is dead at maturity, present in hard areas of the plant. Epidermis is usually a single layered structure present on the entire body surface of the plant. |

|
Answer» Correct Answer - A Cuticle It is a waxy layer present all over the plant body except root. Bulliform cells These are empty colourless cells when the bulliform cells in the leaves absorbed water stress, they make the leaves, curi inwards to minimise water loss. Stomata These are minute apertures in the epidermis, meant for gas exchange. Each aperture is bounded by two kidney shaped cells, called guard calls. Guard cells control closing and opening of stomata Epidermis it is generally uniseriate i.e., composed of single layer of epidermal cells, In some cases epidermis may be multilayered e.g., Ficus, Nerium. |

Answer» Correct Answer - B A meristem or meristematic tissue (Gk. Meristosdivided ) is a simple tissue which can divide parenchyma cells containing chloroplasts are collectively termed as chlorenchyma. It takes part in the maufacture of food (photosynthesis). Storage parenchyma is made of large sized vacuolated cells which store water, mucilage and food, e.g, Aloe, Opuntia, potato tuber. Collenchyma provides mechanical strength to young dicot stems, petioes and leaves. Sclerenchyma is of two types, sclerenchyma fibres and sclereids. Epidermal tissue sytem forms the outermost covering of plant body. It consists of epidermis and epidermal appendages. Epidermis is made of epidermal cells and stomata. |

Answer» Correct Answer - B Meristem It is a group of actively dividing cells which is responsible for the life long growth occuring in the plants Parencyma It is permanent tissues and widely distributed in plant body. It is mainly involved in photosynthesis in chlorophyll containing cells and also store food store food materials Collenchyma The cells of collenchyma tissue have thickening at corners of cells and this provide mechanical strength to herbaceous green stems Sclerenchyma this is dead at maturity, have thickening along all sides of walls. Sclereids and fibre are this types of tissue Epidermal tissue The epidermal tissue system forms the outer most covering of the whole plant body adn comprises epidermal cells, stomata and the epidermal appendages the trichomes and hairs. |
