Non-vascular plants have stems, roots, and leaves.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Non-vascular plants do not have true stems, roots, or leaves. These plants, such as mosses and liverworts, lack specialized tissues for conducting water and nutrients throughout their bodies. Instead, they rely on direct absorption from their surroundings. While non-vascular plants may have structures that function similarly to stems, roots, and leaves, they are not true counterparts to those found in vascular plants. Therefore, the statement that non-vascular plants have stems, roots, and leaves is false.Rate this question:

Vascular plants have vessels that transport food and water to the xylem and phloem.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Vascular plants have specialized structures called vessels that are responsible for transporting food and water throughout the plant. These vessels include the xylem, which transports water and minerals from the roots to the rest of the plant, and the phloem, which transports sugars and other organic compounds from the leaves to other parts of the plant. Therefore, it is true that vascular plants have vessels that transport food and water to the xylem and phloem.Rate this question:

What is the benefit of hydroponics?
- A.
Doubles the crop yield
- B.
Makes the plants greener
- C.
Reduces the use of fertilizer
- D.
Enables crops to grow in areas with poor soil.
Correct Answer
D. Enables crops to grow in areas with poor soil.Explanation
Hydroponics is a method of growing plants without soil, using a nutrient-rich water solution instead. This technique enables crops to be cultivated in areas with poor soil quality, where traditional agriculture may not be feasible. By providing the plants with all the necessary nutrients directly, hydroponics allows them to thrive even in environments where the soil is lacking in essential elements. This benefit of hydroponics opens up opportunities for agriculture in regions with limited access to fertile land, ultimately increasing food production and addressing food security challenges.Rate this question:

All angiosperms
- A.
Are seedless
- B.
Produce fruits
- C.
Have naked seeds
- D.
Are self pollinated
Correct Answer
B. Produce fruitsExplanation
Angiosperms are a group of plants that produce flowers and have enclosed seeds. One of the defining characteristics of angiosperms is their ability to produce fruits. Fruits are the mature ovaries of flowering plants and contain seeds. This adaptation allows angiosperms to protect and disperse their seeds effectively. Therefore, the statement "produce fruits" is a correct characteristic of all angiosperms.Rate this question:

All gymnosperms
- A.
Have a limited growing season
- B.
Are pollinated by birds and bees
- C.
Are colorfull
- D.
Are green year around
Correct Answer
D. Are green year aroundExplanation
Gymnosperms are green year-round because they are evergreen plants. Unlike deciduous plants that lose their leaves in the fall, gymnosperms retain their foliage throughout the year. This allows them to continue photosynthesizing and producing food even during the winter months. The green color is due to the presence of chlorophyll, which is essential for photosynthesis. Gymnosperms include conifers, cycads, ginkgoes, and gnetophytes, and they are known for their ability to thrive in various climates and environments.Rate this question:

Which part of a flower becomes a fruit?
- A.
Ovary
- B.
Petal
- C.
Sepal
- D.
Filament
Correct Answer
A. OvaryExplanation
The ovary is the part of a flower that becomes a fruit. After fertilization, the ovary develops into a fruit, which contains the seeds of the plant. The ovary protects and nourishes the developing seeds, and as the fruit matures, it often becomes fleshy or develops a hard outer layer. This allows the seeds to be dispersed and increases the chances of successful reproduction for the plant.Rate this question:

Which factor helps you to tell the difference between a monocot and a dicot?
- A.
Number of seed leaves
- B.
Number of flower petals
- C.
Arrangement of vascular tissue
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
The factor that helps to distinguish between a monocot and a dicot is all of the above. The number of seed leaves, number of flower petals, and arrangement of vascular tissue are all characteristics that can be used to differentiate between these two types of plants. Monocots typically have one seed leaf, while dicots have two. Monocots often have flower parts in multiples of three, while dicots have flower parts in multiples of four or five. Additionally, the arrangement of vascular tissue differs between monocots and dicots.Rate this question:

List 3 ways that seeds are dispersed.
Correct Answer
animals, wind, waterExplanation
Seeds are dispersed through various means to ensure their survival and distribution. Animals play a crucial role in seed dispersal as they consume fruits or seeds and later excrete them in a different location. This process aids in the spread of seeds over a wider area. Wind dispersal occurs when lightweight seeds are carried away by air currents, allowing them to travel long distances. Water dispersal is another method where seeds are transported through bodies of water, such as rivers or oceans, enabling them to reach new habitats. Therefore, animals, wind, and water are three common ways in which seeds are dispersed.Rate this question:

The leaves of trees change color due to the loss of what pigment.
- A.
Water
- B.
Chlorophyll
- C.
Chromatin
- D.
Photosynthesis
Correct Answer
B. ChlorophyllExplanation
The leaves of trees change color due to the loss of chlorophyll pigment. Chlorophyll is responsible for the green color in leaves and is essential for photosynthesis. As the days become shorter and temperatures drop in the fall, trees stop producing chlorophyll, causing it to break down and be reabsorbed by the tree. This reveals other pigments such as carotenoids and anthocyanins, which give leaves their vibrant fall colors.Rate this question:

What supports the weight of kelp?
- A.
The air
- B.
The ocean
- C.
The wind
- D.
The animals
Correct Answer
B. The oceanExplanation
Kelp is a type of seaweed that grows underwater in the ocean. It is anchored to the ocean floor by a holdfast, which helps support its weight. The ocean provides the necessary buoyancy for the kelp to float and grow vertically towards the surface. The water also helps to distribute the weight of the kelp evenly, preventing it from sinking or being carried away by currents. Therefore, the ocean supports the weight of kelp.Rate this question:

Spikes on a cactus serve what purpose?
- A.
To let oxygen in
- B.
To let oxygen out
- C.
To suck in water
- D.
Defense
Correct Answer
D. DefenseExplanation
The spikes on a cactus serve the purpose of defense. Cacti are often found in arid environments where water is scarce, so their spikes act as a deterrent to prevent animals from approaching and potentially damaging the plant. The spikes can cause pain or injury to predators, making it less likely for them to attempt to eat or disturb the cactus. This defense mechanism helps the cactus to survive and thrive in its harsh habitat.Rate this question:

When do cacti open their flowers?
- A.
Day
- B.
Night
- C.
Both answers above
- D.
Never
Correct Answer
B. NightExplanation
Cacti open their flowers at night. This is because cacti are adapted to arid environments, where daytime temperatures can be extremely high. Opening their flowers at night allows them to conserve water and reduce the risk of dehydration. Additionally, opening their flowers at night increases the chances of pollination, as nocturnal pollinators such as moths and bats are more active during this time. Therefore, the correct answer is "night".Rate this question:
