Plant Adaptations and Traits Assessment

The video discusses the survival challenges faced by species, focusing on adaptive traits in plants. It highlights the oldest known tree and explains how plants adapt to obtain energy, avoid predation, survive harsh environments, and reproduce. The video covers various ecosystems, including deserts and rainforests, and describes traits like dormancy, root structures, and pollination. It concludes with a review of these adaptive strategies.

What is the age of the oldest known organism as of 2023?

• 4,500 years

• 4,855 years

• 5,000 years

• 3,800 years

What is an adaptive trait?

• A behavior learned during an organism's life

• A random mutation in an organism

• A design that an organism starts its life with

• A temporary change in an organism

How do desert plants typically adapt to scarce water availability?

• By growing only during the rainy season

• By having deep roots

• By having shallow and expansive roots

• By growing very tall

What is the main challenge for plants in a tropical rainforest?

• Surviving cold temperatures

• Avoiding being eaten

• Getting enough sunlight

• Getting enough water

What is a common defense mechanism plants use to avoid being eaten by animals?

• Growing thorns or spines

• Producing nectar

• Growing very tall

• Changing color

How do some plants survive being partially eaten?

• By changing their taste

• By growing back the eaten parts

• By producing more seeds

• By moving to a new location

What is biological weathering?

• The process of rocks being worn down by animals

• The process of water freezing and thawing in rocks

• The process of soil erosion by wind

• The process of rocks breaking down due to plant growth

What is dormancy in plants?

• A period of inactivity during harsh conditions

• A period of flowering

• A period of rapid growth

• A period of seed dispersal

How do plants attract animals for pollination?

• By producing seeds

• By growing tall

• By changing color

• By producing nectar and having attractive flowers

What is the role of DNA in adaptive traits?

• It only affects animal traits

• It changes randomly to create new traits

• It is not involved in adaptive traits

• It stores the blueprints for adaptive traits
