A small, seedless non-vascular plant that requires water to reproduce is
What is Bryophytes?
True or False
Angiosperms is split into two groups- Monocots & Eudacot
False, the two groups are Monocots & Eudicot
True or False
Eudicot has a fibrous root system.
False, Eudicot has a taproots that are long.
What are the two classifications of dry fruits?
What is Dehiscent and Indehiscent?
The process of water movement through a plant and evaporations from aerial parts, such as leaves, stems, and flowers.
What is Transpiration?
What are the pteridophyte reproductive structures?
gametophyte, prothallus, sori, spores, antheridia, and archegonium.
What are the characteristics of the gymnosperms?
-Naked seeds
-Adapted to harsh climates
-Needles and scales
Give me two characterizes for Monocot and Dicot.
Monocot: Single Cotyledon, flower parts in 3 or multiples of threes, leaf veins running parallel, and vascular bundles are scattered.
Dicot: two cotyledons, flower parts in multiple of four or five, leaf veins forming a netlike array or pattern, and vascular bundles are in a ring.
What are the two main functions of a fruit is two-fold?
- To protect the developing seed
- To aid in the dispersal of the seed
The long tap root, what is the purpose of it?
Water table deep below ground.
What are some of the characterizes of the Bryophytes?
-Flagellated sperms
-No vascular tissue
-Lack true roots, stems, or leaves
-Gametophyte dominant
One sperm cell of a pollen grain fertilizes an egg cell while a second fuses with two polar nuclei to produce a triploid body that gives rise to the endosperm.
What is Double Fertilization?
The embryonic part of a seed in which stores fuel for further growth.
What is cotyledon?
Can you tell me the importance of seed dispersal?
- So that the seeds can grow into a new plant without excessiveness competition for resources from other plants.
Describe and what are the four transpiration?
-Evaporation: Water changing to gaseous state.
-Cohesion: Water molecules bond to each other.
-Adhesion: attracted to other molecules.
-Absorption: Roots soaking up water from ground.
The lack of true roots is an advantage for the bryophytes because
It allows them to grow on substrates where there is no soil.
Describe how the Angiosperms reproduction process works?
First, pollen falls onto the flower's stigma because of pollination. Second, sperm cell joins with the egg cell inside the ovary due to fertilization. Third, Zygote develops in the seed. Then the ovary ripens and developed into a fruit. Lastly, the seeds are dispersed into new areas
Rudbeckia hirta is this a monocot or dicot flower? Why?
This a monocot flower because it has parallel leaves even though it has about 13 petals.
1.Consists of a single seed that is attached to the wall of the ovary at only one point.
2. Dry indehiscent fruit that is thin, transparent and firmly attached to all points of the seed coat.
3. A wind borne fruit containing a single seed.
1. What is Achene?
2. What is Grain?
3. What is Samara?
What are several factors that are affected by the transpiration rate?
- Temperature
- Light intensity
-Humidity
-Wind speed
Give me four similarities between the ferns and mosses life cycle.
- Stomata or pores are present in both groups for gaseous exchange.
- Reproduce asexually by spores in the sporangium.
- Water is essential for fertilization
- The zygote retains the archegonium after fertilization.
Describe how an animal could assist in pollinating flowers.
Animals feed on the flower nectar become coating with pollen. Also, they pollinate flowers by brushing pollen onto the flower's stigma.
Nelumbo nucifera, what kind of flower is it monocot or dicot? why?
This Lotus flower is both monocot and dicot plant. Because they have characterizes that contain monocot and dicot. For instances, the Lotus seeds contain a embryonic plant indicating its a dicot. However, it has a hairy roots of a monocot characterizes.
What are the characteristics of a simple, aggregate, and multiple fruits? Give an example of each one.
Simple: One flower that only has one pistil. Example: Apple
Aggregate: One flower that has several pistils. Example: Raspberry
Multiple: Forms from several flowers. Example: Pineapple
Give at least 4 benefits of transpiration.
- Creates a turgor pressure which will provide support.
- The plant has a persistent supply of water that can be used for photosynthesis.
- It assists in the exchange of gases.
- Provides coolness to the plants body.
