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
Botany:
Types of Pollination:
1. Complex type of pollination
2. Allows the transfer of pollen grains from the anther of the flower into the stigma of another flower.
3. Leads to an increase in genetic diversity as different flowers will share and combine their genetic information to create unique offspring.
Cross-Pollination
Botany:
Types of Cross-Pollination:
1. Pollination that uses wind.
Anemophily
Botany:
Types of Cross-Pollination:
1. Pollination that uses animals.
Zoophily
Botany:
Types of Cross-Pollination:
1. Artificial pollination done by human beings.
Anthropophily
Botany:
1. Ripened ovary of a part containing the seeds.
Fruits
Botany:
Plant Structure:
1. The wall of the ovary that dveelops as the wall of the fruits.
Pericarp
Botany:
Plant Structure:
1. Ripened fertilized ovules in fruits.
Seeds
Botany:
1. When a plant exhibits some growth movement in response to a stimulus.
Tropism
Botany:
Classification of Tropism
Positive and Negative Tropism
Botany:
Classification of Tropism:
1. When the movement of a plant is toward the direction of stimuli.
Positive Tropism
Botany:
Classification of Tropism:
1. When the movement of a plant is away from the stimuli.
Negative Tropism
Botany:
Types of Tropism:
1. Plant grow towards or away from the light.
Phototropism
Botany:
Types of Tropism:
1. Also referred tp as ‘geotropism’
2. A type of tropism where plants show some growth in response to gravity.
Gravitropism
Botany:
Types of Tropism:
1. When plants grow in response to certain chemicals.
Chemotropism
Botany:
Types of Tropism:
1. The growing or developing movement made through plants in contact with a solid object.
2. Usually seen in tendrils.
Thigmotropism
Botany:
Types of Tropism:
1. The movement or the growth of a plant in relation to the stimulus of water.
Hydrotropism
Botany:
Types of Tropism:
1. The form of tropic movement in which a plant or a part of the plant responds to the changing atmospheric temperature.
Thermotropism
