Anther
a sac-like structure at the top of the stamen that contains pollen
Apical Meristem
Primary growth area in stems.
Cellular respiration
chemical reaction in which stored food energy is made available for plants and animals
Chloroplast
An organelle found in plant and algae cells where photosynthesis occurs.
Fertilization
the joining of a sperm cell and an egg cell
Filament
the thin stalk that holds up the anther
Flower
the reproductive organs of a plant
Fruit
the reprodicutive body of a seed plant consisting of one or more seeds and usually various protective and supporting structures
Leaf
an outgrowth from a plant that constitutes part of the foliage and functions primarily in food manufacture by photosynthesis
Ovary
the lower part of the pistil that contains one or more ovules or the part in which the eggs are produced and seeds develop
Petal
leaf-like strucutres located inside the sepals that are often colorful
Photosynthesis
the manufacture of food by green plants in which carbon dioxide and water are combined in the presence of light and chlorophyll to form sugar and oxygen
Pistil
the female reproductive parts of the flower
Pollination
the transfer of pollen from the anther to the stigma of the flower

Style

Clay
fine-grained soil; smallest soil particle
Complete fertilizer
contains all three of the primary fertilizer nutrients (nitrogen, phosphorus, and potassium)
Fertilizer
