Undifferentiated tissue that exhibits growth, usually in buds, shoots, and root tips.
A roughly spherical underground structure containing several buds that can give rise to new plants.
A waxy covering on the surface of stems and leaves that acts as an adaptation to prevent desiccation in terrestrial plants.
A hormone that stimulates fruits to ripen, leaves to fall, buds and seeds to end dormancy, and horizontal root or stem growth.
The gamete-producing haploid phase in the life cycle of a plant having alternation of generations.
A hormone that causes growth in roots and stems while encouraging germination of seeds and buds.
A hormone that encourages growth and the development of chloroplasts, fruits, and flowers. Additionally, it delays senescenes.
The tissue of a leaf between the upper and lower epidermis specialized for photosynthesis.
A symbiotic relationship where a fungus binds to a plant root and helps the plant absorb water and minerals better, while the fungus receives more carbohydrates.
The upper layer of the mesophyll, in which cells are tightly packed and their chloroplasts arranged in vertical columns.
Living vascular tissue that distributes the products of photosynthesis. They have sieve elements that are controlled by companion cells.
The ovule-producing female part of the flower. It contains the stigma, the style, and the ovary.
A soft spongelike central cylinder of the stems of most flowering plants, made up of parenchyma cells.
Also the rhizoid, these tubular outgrowths in the mature region of the root help the plant absorb more water and nutrients.
A horizontal stem that extends outwards from the main plant. Nodes located at intervals can give rise to new plants.
The lower layer of the mesophyll which is less ordered and more diffuse, allowing a greater exchange of gasses.
The spore-producing diploid phase in the life cycle of a plant having alternation of generations.
A flattened membrane sac inside the chloroplast, used to convert light energy into chemical energy.
