12 Questions
What type of plants have vascular tissue?
Lycophytes and Pteridophytes, Gymnosperms, Angiosperms
Which plant group produces 'naked seeds' or cones?
Gymnosperms
What type of plants have leaves that are lost during the fall?
Angiosperms
Which plant group has a reproductive structure called 'flowers'?
Angiosperms
What type of plants grow low to the ground and require high moisture in the soil?
Bryophytes (Mosses)
Which plant group lacks vascular tissue?
Bryophytes (Mosses)
What are the 3 primary (non-reproductive) organs of a plant?
Leaves, Stems, and Roots
What are the 2 organ systems in plants and what do they do?
Shoot System: Everything above ground (stems, leaves, flowers, and fruit) Root System: Everything below ground
What are the 4 layers of plant tissue and their functions?
Epidermal – protective outer covering, prevents water loss and allows for gas exchange. Ground – (3 main types) makes up most of the plant; used for food storage, structural support, and photosynthesis. Vascular – for transport Xylem – transport of water and minerals Phloem – transport of sugars made during photosynthesis Meristematic – Unspecialized, capable of mitosis for new growth. Can develop into any other type of plant tissue
What is the function of xylem in plants?
Transport of water and minerals
What is the role of phloem in plants?
Transport of sugars made during photosynthesis
What is the significance of meristematic tissue in plants?
Unspecialized, capable of mitosis for new growth. Can develop into any other type of plant tissue
Study Notes
Types of Plants
- Vascular plants, such as tracheophytes, have vascular tissue that allows for transportation of water and nutrients.
- Gymnosperms, such as conifers and cycads, produce 'naked seeds' or cones.
- Deciduous plants, such as oak and maple trees, have leaves that are lost during the fall.
- Angiosperms, such as flowering plants, have a reproductive structure called 'flowers'.
Plant Characteristics
- Bryophytes, such as mosses and liverworts, grow low to the ground and require high moisture in the soil.
- Non-vascular plants, such as bryophytes and algae, lack vascular tissue.
Plant Organs and Systems
- The 3 primary (non-reproductive) organs of a plant are roots, stems, and leaves.
- The 2 organ systems in plants are the root system and the shoot system, which are responsible for absorption and transportation of water and nutrients, and photosynthesis and growth, respectively.
Plant Tissue
- The 4 layers of plant tissue are epidermis, cortex, sclerenchyma, and parenchyma, which provide protection, storage, support, and photosynthesis respectively.
Plant Functions
- Xylem tissue is responsible for transporting water and minerals from roots to leaves.
- Phloem tissue is responsible for transporting sugars and nutrients produced by photosynthesis from leaves to the rest of the plant.
- Meristematic tissue is responsible for plant growth and development, as it has the ability to differentiate into different cell types.
