|---|
| photosynthesis | process plants use to make food |
| palisade layer | most photosynthesis takes place in this leaf layer |
| cellular respiration | process by which plants release energy in food to carry on life processes |
| tropism | a plant's response to stimulus |
| phototropism | when a plant grows toward the light |
| gravitropism | how a plant knows to grow seeds down into the soil |
| fertilization | the joining of an egg and sperm cell |
| stamens | male part of flower that produces seeds |
| tissue culture | growing new plants from plant tissues |
| pistil | the female part of a flower that contains its reproductive cells |
| ovary | a part of the pistil that contains eggs in one or more section, called the ovule |
| embryo | a tiny plant that can grow into a mature plant |
| cotyledons | structures inside a seed that store food |
| germinate | sprout |
| seedling | an embryo plant that has emerged from its seed and is using energy from the cotyledons |
| grafting | a form of artificial reproduction that involves attaching branches from one plant to the branches of another plant |
| vegetative propagation | ability of some plants to reproduce without seeds |
| stomata | opennings in the lower epidermis |
| guard cells | edges of the stomata |
| cuticles | a waxy covering on the epidermis |
| spongy layer | layer of leaf under palisade, with loosely packed cells |
| chlorophyll | transforms light energy into chemical energy |
| cross pollination | pollination between two different flowers |
| grafting | a from of artificial reproduction that can produce desirable characteristics in woody plants |
| pollination | the transfer of pollen from anther to stigma |
| touch tropism | a plant's response to touch |
