For each treatment‚ we obtained two planting trays with cell flats- in which one corner cell was cut out to water the plants. We filled all cell flats with the fertilized soil and used forceps to place one seed with 3-4mm deep in the middle of each cell. After all trays of cells were planted‚ we brought these trays in a growth room and watered the plants. In the growth room‚ the amount of light‚ the temperature‚ and the humidity was kept the same for both

include in phylum Anthophyta.Angiosperms are plant that have flowers and fruit. Their part of the flower is a carpel which surrounds and protects the ovules and seeds. The fruit surrounds the embryo and aids seed dispersal. The great majority of angiosperms are classified either as monocots or eudicots.Monocot embryos have a single seed leaf (cotyledon)‚ and pollen grains with a single groove while eudicots (true dicots) have two cotyledons‚ and pollen grains with three groove. Monocotyledons have

The most difficult form of propagation is grafting. A lot of people probably think this is dumb or boring‚ but I think it is neat. Most people think the only way to grow plants is by seed‚ but you can also use leaves‚ and stems. Sean Russell says” Plants naturally use several different methods to multiply‚ from seeds to spores to shoots. Gardeners looking to speed the process along can propagate new plants from cuttings. Cuttings are a part of a plant’s roots‚ branches or leaves that‚ when cut and

The female cones found near the center of the pine tree while the male cones are located near the tips of the branches. When the seeds mature‚ they grow a single “wing” that lets them to spin as they slowly fall from the female cone. Male Cones ready to cast pollen Female cones receptive for pollination

Plants need the insects to carry the pollen to seeds. Since the neighbor sprayed insecticide because the Japanese beetles attacked their rose garden‚ there are no insects there to carry the pollen. Fruits won’t form unless the flowers are pollinated. Insects are considered pollinators for plants‚ without them the pollen would not go around. Pollination is needed to produce new seeds and create a wide variety of plants. 4. Table 16.7 Uses of Seeds Plants: Angiosperms and Gymnosperms Uses of
