Midterm Flashcards
What is the definition of a plant?
A plant is a living organism that typically produces its own food through photosynthesis and has a cellular structure that includes cell walls made of cellulose.
Plants are essential for life on Earth as they produce oxygen and are a primary food source for many organisms.
What are the types of Vascular Tissue?
- Xylem
- Phloem
Vascular tissue is crucial for transporting water, nutrients, and food throughout the plant.
Why is Vascular Tissue important?
It is important for the transport of water, nutrients, and sugars, which are essential for plant growth and development.
Vascular tissue allows plants to grow larger and live in diverse environments.
What is the definition of a seed?
A seed is a fertilized ovule that contains an embryo, a food supply, and a protective seed coat.
Seeds are essential for the reproduction and dispersal of many plant species.
What are some advantages of seeds?
- Protection of the embryo
- Nutritional support for the embryo
- Facilitation of dispersal
- Dormancy for survival in adverse conditions
Seeds allow plants to spread their offspring over distances and survive unfavorable conditions.
What are some seed dispersal mechanisms?
- Wind
- Water
- Animals
- Gravity
Different mechanisms help in spreading seeds to new locations, enhancing the chances of plant survival and colonization.
What do growth rings in wood represent?
Growth rings represent the annual growth of a tree, indicating age and environmental conditions during each year of growth.
The width of growth rings can indicate periods of drought or abundant growth.
What are the types of fruit?
- Simple fruits
- Aggregate fruits
- Multiple fruits
Each type of fruit has different characteristics and methods of development.
What is flower anatomy?
Flower anatomy includes structures such as petals, sepals, stamens, and carpels.
Each part of a flower plays a role in reproduction and attracting pollinators.
How can you match Native Ferns and Native Conifers?
By identifying major characteristics such as leaf shape, growth form, and reproductive structures.
Understanding these characteristics helps in recognizing different species.
What are the characteristics of Monocots?
- One seed leaf (cotyledon)
- Parallel leaf venation
- Flower parts in multiples of three
Monocots include grasses, lilies, and orchids.
What are the characteristics of Dicots?
- Two seed leaves (cotyledons)
- Netted leaf venation
- Flower parts in multiples of four or five
Dicots include roses, sunflowers, and oaks.
Name an edible plant.
Examples include tomatoes, potatoes, and spinach.
Edible plants are crucial for human nutrition and food security.
Name a medical plant.
Examples include willow (for aspirin) and foxglove (for digitalis).
Many plants have medicinal properties that have been used in traditional and modern medicine.
Name a toxic plant.
Examples include poison ivy and deadliest nightshade.
Toxic plants can cause serious health issues if ingested or touched.
What are some major food plants?
- Rice
- Wheat
- Corn
These plants are staples in diets around the world.
What are some major drug plants?
- Opium poppy
- Cannabis
- Coca plant
These plants are sources of substances used for medicinal and recreational purposes.
What are some major textile plants?
- Cotton
- Flax
- Hemp
These plants are grown for their fibers, which are used in making fabrics.
