Plants 79. What system do these plant parts belong to? Root system or shoot system Leaf –shoot system Stem- shoot system Roots- root system

Plant Tissue The vascular system of a plant is most like the circulatory system of the animal in that is transports nutrients and waste throughout the plant. The Xylem carries Water The Phloem carries Food- (ph-f) You can think the dermal tissue of a plant like the skin (dermis & epidermis) of a human. It is a thin layer that covers the inner tissue of a plant

Transpiration is the loss of water through the stomata in a leaf Plant Homeostasis Transpiration is the loss of water through the stomata in a leaf Guard cells control the opening and closing of stomata. Usually associated with gas exchange. When stomata are open, water is lost In extremely dry weather stomata will close to preserve water.

Plant responses Phototropism causes the cells on the dark side of a plant to elongate and bend toward the light. Thigmotropism is the plants response to touch. Such as a vine Geotropism/gravitropism is the plant growing towards or away from the earth as a result of gravity. Root systems grow with the force of gravity (positive tropism), shoot systems grow opposite the force of gravity (negative tropism)

Plant reproduction Gymnosperms and Angiosperms both reproduce sexually Gymnosperms have cones containing male gametes and female cones with the female gamete Angiosperms have flowers with male and female structures (pistil and stamen) Both depend on wind, water, or pollinators to spread the gametes to other plants for pollination Ferns & Moss reproduce by releasing millions of spores. This is asexual reproduction

This feedback mechanism reacts to changes in the body and provides necessary means to return the body to normal. Nervous system Circulatory Integumentary Endocrine Muscular
