Term | Definition |
---|---|
alternation of generations | plant life cycle |
dermal tissue | covers the outside of a plant |
gametophyte | Plants in the haploid generation.They have male and/or female reproductive organs and reproduce sexually. |
ground tissue | makes up much of the inside of a plant |
leaf | the keys not only to plant life but to virtually all life on land. The primary role is to collect sunlight and make food by photosynthesis |
plant | multicellular eukaryotes |
Plant Kingdom | comprising of all living or extinct plants |
root | important organs in most modern plants. They absorb water and minerals, anchor and support the plant, and store food. |
sporophyte | Plants in the diploid generation. They reproduce asexually. |
stem | organs that hold plants upright |
stoma (stomata, plural) | pores in the epidermis of the leaf or stem of a plant |
transpiration | They release water vapor to the air from their leaves |
vascular tissue | runs through the ground tissue inside a plant |
angiosperm | seed plants that produce seeds in the ovaries of flowers |
cone | reproductive structures made of overlapping scales |
embryo | a zygote that has already started to develop and grow |
flower | plant structures that contain male and/or female reproductive organs |
fruit | As seeds develop, the ovary turns into this |
germination | Early growth and development of a plant embryo inside a seed |
gymnosperm | seed plants that produce naked seeds in cones |
petal | Usually the most visible parts of a flower |
pistil | The female reproductive organ in a flower |
pollen | a tiny male gametophyte enclosed in a tough capsule |
pollinator | an animal that picks up pollen on its body and carries it directly to another flower of the same species |
seed | a reproductive structure that contains an embryo and a food supply |
stamen | The male reproductive organ in a flower |
aquatic plant | Modern plants that live in water |
carnivorous plant | plants that get some or most of their nutrients (but not energy or carbon compounds) from other organisms |
epiphyte | grow on other plants |
gravitropism | response to gravity |
phototropism | response to light |
tropism | turning toward, or away from, a stimulus in the environment |
xerophyte | Plants that are adapted to very dry environments |
