100
The transfer of pollen grains from an anther to a stigma.
Pollination?
100
Phloem sap is transported from ___ to ___
Source to sink.
100
What is the embryo of a plant called?
A seed.
100
What is tropism?
The growth or turning movement of a plant in response to a directional external stimulus.
100
Phytochrome controls ___.
Photoperiodism.
200
The process by which a seed emerges from a period of dormancy and begins to sprout.
Germination?
200
What are three ways minerals and ions travel through the soil?
Fungal Hyphae, diffusion, mass flow of water.
200
Ferns are a part of what category of plants?
Filicinophyta, (Pterophyte)
200
What is responsible for the increase in diameter of plant cells?
Lateral Meristem
200
Transport of phloem sac is called____.
Active Translocation.
300
The male part of a flower is called the ____ and is composed of the ___ and ____?
Stamen, Anther, Filament?
300
What are some adaptations of roots to increase water and mineral absorption?
Branching and root hairs create a larger surface area for absorption, protein pumps to move minerals against their concentration gradient.
300
What are three differences between the structures of monocotyledonous plants and dicotyledonous plants?
1 cotyledon vs 2, parallel veins in leaves vs net-like veins, flowers have multiples of 3 petals vs 4 or 5, vascular tissue vs ringed tissue.
300
What is responsible for the growth and elongation of the roots and the stems of plants?
Apical Meristem
300
What is a xerophyte and give an example
A plant that lives in extremely dry conditions; a cactus.
400
The female part of a flower is called the ___ and is composed of the ___, ____, and ____?
Pistal (or carpal), stigma, style, ovule?
400
Outline 4 adaptations of xerophytes and how they reduce transpiration
Thick waxy cuticle holds water in, spines reduce SA for transpiration, reduced number of stomata so there’s a decrease in the rate of transpiration, CAM Physiology, stomata open at night to reduce evaporation.
400
Compare Filicinophyta and Coniferophyte
Both are vascular plants, filicinophyta reproduce through spores on the ferns and coniferophyte reproduce through seeds and cones.
400
How does auxin play a role in the control of plant growth?
Auxin is a hormone that targets the apical bud of a plant that detects light, it diffuses to the shady part of the stem and causes elongation of those cells towards the direction of the sun (light).
400
What hormone is responsible for seed germination?
Gibberellin
500
Distinguish between pollination, fertilization, and seed dispersal
Pollination: Transfer of pollen from an anther to stigma, Fertilization: Fusion of a male gamete nuclei and a female gamete nuclei in the ovule, Seed Dispersal: Fertilization results in the formation of a seed which leaves the parental plant and competes for germination.
500
What is the effect of 3 external factors on the rate of transpiration?
Wind: Increases transpiration by blowing water away from stomata, Temperature: Higher temperatures increase transpiration because water around the stomata evaporates, Humidity: High humidity levels decrease the rate of transpiration because air holds the water in and causes the rate of evaporation to decrease.
500
What are the 4 layers of tissues in a plant called, and what is their function?
Upper Epidermis: Water conservation, Vascular Tissue: transport (xylem and phloem), Palisade Mesophyll: photosynthesis, Spongy Mesophyll: Gas exchange.
500
Outline 3 conditions necessary for a germination of a seed.
Oxygen: Aerobic respiration for ATP, Water: metabolic activation of cells, Temperature: so, enzymes can function.
500
Place pollination, seed dispersal, and fertilization in order.
Pollination, fertilization, seed dispersal.
