6). Meristematic tissue has a number of defining features, including small cells, thin cell walls, large cell nuclei, absent or small vacuoles, and no intercellular spaces. The apical meristem (the growing tip) functions to trigger the growth of new cells in young seedlings at the tips of roots and shoots and forming buds.

7)...and 7 refer to the attachment...pls..

8)... How are simple tissues different from complex tissues in plants?

A simple tissue is composed of only one type of cells while the complex tissue is composed of different types of cells.

9)...It forms a boundary between the plant and the external environment. The epidermis serves several functions: it protects against water loss, regulates gas exchange, secretes metabolic compounds, and (especially in roots) absorbs water and mineral nutrients.

10)...@ )...Areolar connective tissue holds organs in place and attaches epithelial tissue to other underlying tissues. It also serves as a reservoir of water and salts for surrounding tissues. Almost all cells obtain their nutrients from and release their Ciliated epithelium is a thin tissue that has hair-like structures on it. These hairs, called cilia, move back and forth to help move particles out of our body. into areolar connective tissue.

b)..Ciliated epithelium is a thin tissue that has hair-like structures on it. These hairs, called cilia, move back and forth to help move particles out of our body.

c)...Ligaments are short bands of tough, flexible tissue, made up of lots of individual fibres, which connect the bones of the body together. Ligaments can be found connecting most of the bones in the body. The function of a ligament is to provide a passive limit to amount of movement between your bones.

d)..The thickened walls of the collenchyma cells enable them to provide additional support to the areas where they are found. Most notably, collenchyma cells serve growing parts of the plant, such as shoots and leaves, both by providing support and by filling in vacant spaces that will be used for later growth.

e)....The main function of striated muscle tissue is to create force and contract. These contractions will either pump blood throughout the body (cardiac muscle) or powers breathing, movement or posture (skeletal muscle).
