Plantae Flashcards
Are plants multicellular?
Yes
What is plants cell wall made of?
Cellulose.
Are plants Eukaryotes or Prokaryotes?
Eukaryotes.
Are plants unicellular or multicellular?
Multicellular.
How do plants reproduce?
Sexually.
What is other characteristic of plants?
They can’t move
What are the main parts of plants?
Roots, leaves, stems, and reproductive organs.
What is the function of roots?
To absorb minerals and water from the soil. They also anchor the plant.
What is the function of leaves?
To carry out photosynthesis with increased surface area.
What is transpiration? How does it occur?
It’s a process of plants losing water due to the openings called stomata. Stomatas are tiny holes in leaves that are used to absorb gases (CO2) for photosynthesis. Guard cells surround stomata.
How is a waxy covering on plants called?
A cuticle.
What is the function of stem?
It hold leaves and has vascular tissue inside to transport nutrients.
How two types of hollow tissues that transport nutrients are called?
Xylem and Phloem.
What is the function of Xylem?
It transports nutrients and water from the soil to the leaves for photosynthesis.
What is the function of Phloem?
It transports photosynthesis products (sugar) from the leaves down the rest of the plant.
What did plants develop when they moved to the land from the sea?
They developed seeds to protect and provide nutrients for their embryo in dry env. They also developed vascular tissue to transport water up from the soil, and to preserve this water their developed cuticle. Roots were also developed
What are the main 4 groups that plants are classified into? How do they get classified?
Non-vascular plants (Bryophytes), Seedless Vascular, and Seed-producing Vascular (Gymnosperms and Angiosperms).
They are classified by the presence of absence of vascular tissue, and presence or absence of seeds.
What are the characteristics of Bryophytes? How do they reproduce? Examples?
They don’t have vascular tissue and get water from diffusion. They hold onto things by rhizoids. Bryophytes reproduce by spores. Examples are mosses and liverworts.
What are the characteristics of Seedless Vascular? Examples?
They have Phloem and Xylem to transport nutrients and water and use spores to reproduce. Examples are ferns and horsetails.
What are the characteristics of Gymnosperms? Examples?
Gymnosperms are non-flowering plants that produce cones as reproductive structures. Examples are conifers and ginkgos.
How do Gymnosperms reproduce?
Pollen from male cones pollinates eggs on famale cones.
What are the characteristics of Angiosperms? Examples?
Angiosperms are flowering plants that have seeds developed inside a protective structure. Example is sunflower.
What are 2 classifications of Angiosperms?
Monocots and Dicots.
What do male and female gamets form?
A zygote.
