A multicelled photoautotroph, most with well-developed roots and shoots (e.g., stems, leaves), as well as photosynthetic cells that include starch grains as well as chlorophylls a and b, and polysaccharides such as cellulose, pectin, and lignin in cell walls. The primary producers on land.
plant that absorbs water and other substances directly thorugh its cells
plants with tubes
the study of plants
stems, roots, leaves
Absorbs water and minerals from the ground. Anchors plant in ground.
tiny hair-like extensions that increase the surface area of the root allowing it to absorbs more water and nurtients
Vascular plant tissue consisting mainly of tubular dead cells that conduct most of the water and minerals upward from roots to the rest of the plant.
vascular tissue responsible for the transport of nutrients and the carbohydrates produced by photosynthesis
the main parts of a plant that support the leaves and flowers and transports
soft green and flexable stems
grows, reproduces and dies in the growing season
Hard and rigid-xylem and phloem tissues are in rings
lasting for a long time, persistent; a plant that lives for many years
vascular tissue that produces xylem and phloem cells as a plant grows
The main photosynthetic organs of vascular plants.
A waxy covering on the surface of stems and leaves that acts as an adaptation to prevent desiccation in terrestrial plants.
waxy layer on leaf prevents water loss
The tightly packed photosynthetic cell found just under the epidermus in many leaves.
a minute epidermal pore in a leaf or stem through which gases and water vapor can pass
cells that control the opening and closing of stomata
the loss of water through leaves
Moist, loosely packed layer of cells containing chloroplasts.
broad, flat leaves and hard wood trees that lose their leaves each fall and are bare all winter:sycamore is the largest
a tree that does not lose its leaves in the winter, and stays green all year round
food making progress in plant
the first stage of photosynthesis during which energy from light is used for the production of ATP
the second stage of photosynthesis that starts with ATP, NADPH, and Carbon dioxide and produces glucose
series of chemical reactions used to release energy stored in food molecules
a change in an organism's surroundings that causes the organism to react
positive or negative plant response to an external stimulus such as touch, light, or gravity
the growth of a plant part toward or away from light.
stem grows away from gravity
response to earth's gravity, as the growing of roots downward in the ground
Hormones for plant elongation and rooting
plants that produce seeds for reproduction
An undeveloped plant with stored food sealed in a protective covering
a seed plant that produces naked seeds, does not produce flowers or fruit and has a deep growth
A flowering plant, which forms seeds inside a protective chamber called an ovary
Single cotyledons (embryonic seed leaf). Flower parts in 3s or multiples of 3s, vascular tissue in scattered bundles, fibrous root system, leaves with parallel veins.
Two cotyledons. Flower parts in fours or fives, vascular tissue in distinct bundles arranged in a circle, taproot system, leaves with netted veins.
a seed leaf that stores food
process in sexual reproduction in which male and female reproductive cells join to form a new cell
the transfer of pollen from male reproductive structures to female reproductive structures in plants
the fine spores that contain male gametes and that are borne by an anther in a flowering plant
The reproductive structures of plants
a flower lacking on one or more reproductive organs
Contains both stamen (male) and pistil (female) parts
the male reproductive organ of a flower
the part of the stamen that contains pollen
the stalk of a stamen
the female ovule-bearing part of a flower composed of ovary and style and stigma
the apical end of the style where deposited pollen enters the pistil
(botany) the narrow elongated part of the pistil between the ovary and the stigma
the organ that bears the ovules of a flower
Structure that develops within ovary of seed plant and contains female gametophyte.
modified leaves which are usually bright in color to attract pollinators.
Leaflike parts that cover and protect the flower bud
the process whereby seeds or spores sprout and begin to grow
