Roots, Flowers, Fruits, Pollination, & Tropism Flashcards
Botany:
Plant Structure:
1. Underground vascular plants that anchors the plant firmly.
2. Absorbs water and minerals.
Roots
Botany:
Plant Structure:
1. Root extensions that increases the surface area of a root to improve water absorption.
Root Hair
Botany:
Plant Structure:
1. Tiny cap-like structures present at the tip of a growing root.
2. It protects the growing tip in plants.
Root Cap
Botany:
Plant Structure:
Root Systems:
1. Have a main central root upon which root hairs are attached.
Taproot System
Botany:
Plant Structure:
1. The reproductive part of a plant.
Flower
Botany:
Plant Structure:
Root Systems:
1. Roots that arise from other than the radicle like stems and leaves.
Adventitious Roots
Botany:
Plant Structure:
Root Systems:
1. Bushy roots in which thin, moderately branching roots grow from the stem.
Fibrous Root System
Botany:
Plant Structure:
1. Inner to the sepals that are bright-colored part that attracts insects.
2. The collective unit is called corolla
Petals
Botany:
Plant Structure:
1. Outer to the petals that is green-colored.
2. The collective unit is called calyx
Sepals
Botany:
Plant Structure:
1. The male reproductive part of flowers.
2. Consists of the anther and filament.
Stamen
Botany:
Plant Structure:
Flower - Stamen:
1. Sac-like structures, involved in producing and storing the pollens.
Anther
Botany:
Plant Structure:
Flower - Stamen:
1. Slender, threadlike object that holds and supports the anther.
Filament
Botany:
Plant Structure:
1. Also known as ‘carpel’
2. The female reproductive part.
2. Consists of the stigma, style, ovary, and ovules.
Pistil
Botany:
Plant Structure:
Flower - Pistil:
1. The topmost part that helps collect pollen
Stigma
Botany:
Plant Structure:
Flower - Pistil:
1. The long tube-like slender stalk that connects the stigma and the ovary.
Style
Botany:
Plant Structure:
Flower - Pistil:
1. Found at the base of the pistil that contains the ovules.
Ovary
Botany:
Plant Structure:
Flower - Pistil:
1. Organ that forms the seeds.
Ovules
Botany:
Plant Structure:
Flower Classification:
1. A flower that has both male and female parts.
Perfect Flower
Botany:
Plant Structure:
Flower Classification:
1. A flower that only has male or female parts.
Imperfect Flower
Botany:
Plant Structure:
Flower Classification:
1. Flower that contains sepals, petals, pistils, and stamens.
Complete Flower
Botany:
Plant Structure:
Flower Classification:
1. Flower that is missing one of the parts: sepals, petals, pistils, and stamens.
Incomplete Flower
Botany:
1. method where pollen grains are picked from an anther and transferred to the stigma.
Pollination
Botany:
Types of Pollination
Self-Pollination and Cross-Pollination
Botany:
Types of Pollination:
1. Primary type of pollination as it includes a single flower.
2. Occurs when pollen grains fall directly from anther into the stigma of the flower.
3. Simple and fast
4. Leads to a reduction in genetic diversity as the sperm and egg cells of the flower share some genetic information.
Self-Pollination
