Type of vascular tissue in plants that carries water and minerals up from roots; made of vessel elements and tracheids
Type of vascular tissue in plants that carries nutrients from leaves and any other photosynthesizing cell downwards; composed of companion cells and sieve-2 members
Living elongated cells used for support; generally used in young plants or in the growing parts of plants
Top and bottom layer of cells on a leaf; secretes a waxy cuticle onto the surface of the leaf; makes the leaf waterproof
Pores on the bottom of a leaf that help plants undergo gas exchange (water vapor and oxygen leave, CO2 comes in)
Type of meristematic tissue located between xylem and phloem that makes xylem and phloem
Hormone in plants responsible for tissue differentiation and breaking seed dormancy (wakes a seed up when the conditions are right for it to begin germination)
Hormone in plants that promotes rapid growth in the early life of a plant; also promotes the growth involved in germination
Hormone in plants that promotes dormancy (EX: causes the leaves to fall off in the winter)
Hormone in plants responsible for fruit ripening (fruit releases this gas and it causes the fruit to ripen)
A plant growing towards a light source; auxin causes cells on the dark side of the plant to elongate towards the light
Plants growing towards touch (EX: a vine wrapping around a tree; must be constantly in contact with it)
Third phase of life cycle
Spore develops by mitosis into a multicellular organism called the gametophyte
Fourth phase of life cycle
Gametophyte produces many haploid gametes (male and female, sperm and ovum respectively) by mitosis
Fifth phase of life cycle
Haploid gametes fuse in the process of fertilization to form the diploid zygote
Condition of most plants; sporophyte is much bigger and longer lasting than the gametophyte (spends more time being a sporophyte than a gametophyte)
