1. A leaf with 2 or more leaflets is called a ______________________ leaf.

Explanation

A leaf with 2 or more leaflets is called a compound leaf. This is because a compound leaf consists of multiple leaflets attached to a single leaf stalk or petiole. Each leaflet in a compound leaf is typically arranged in a specific pattern, such as pinnate or palmate. This arrangement allows the leaf to capture more sunlight and perform photosynthesis more efficiently. In contrast, a simple leaf only has one leaf blade attached to the petiole.

2. When a leaf blade is single and undivided the leaf is considered___________________.

Explanation

When a leaf blade is single and undivided, it is considered simple. This means that the leaf is not divided into separate leaflets. A simple leaf typically has one blade attached to the petiole, which is the stalk that connects the leaf to the stem. In contrast, a compound leaf is divided into separate leaflets, each with its own stalk, called a petiolule. Therefore, based on the given information, the correct answer is simple.

Submit
3. Some plants have leaves that are arranged in a circle AROUND the stem, this leaf arrangement is called________________.,

Explanation

Whorled leaf arrangement refers to the pattern where three or more leaves are arranged in a circular manner around the stem. This arrangement can be observed in certain plant species where the leaves are positioned at different heights along the stem, forming a circular pattern. This arrangement is different from opposite leaf arrangement, where two leaves are positioned directly across from each other on the stem, and alternate leaf arrangement, where leaves are positioned singly at different heights along the stem.

Submit
4. Leaf _________________carry water to the cells of a leaf and carry the sugar that is made in the leaves to other parts of the plant.

Explanation

Veins in a leaf are responsible for carrying water to the cells of the leaf and transporting the sugar produced in the leaves to other parts of the plant. Veins act as a network of vessels that distribute nutrients and water throughout the leaf, ensuring the proper functioning and growth of the plant. The other options, such as eyes, blades, and leaflets, do not have a role in the transportation of water and sugar within a leaf.

Submit
5. A simple leaf is a leaf that is ______________ and __________________.

Explanation

A simple leaf is a leaf that is single and undivided, meaning it consists of a single leaf blade that is not divided into separate leaflets. This is in contrast to compound leaves, which are divided into multiple leaflets. The terms "single" and "undivided" emphasize the unity and integrity of the leaf structure, indicating that it is not composed of separate parts or subdivisions.

Submit
6. Monocots have leaves with______________________veins.

Explanation

Monocots have leaves with parallel veins. This means that the veins in the leaf run parallel to each other, without branching or intersecting. This is in contrast to dicots, which have leaves with branching veins. The parallel arrangement of veins in monocot leaves allows for efficient transport of water, nutrients, and sugars throughout the leaf.

Submit
7. When leaves are attached on opposite sides, but NOT directly opposite of each other, the leaf arrangement is called_______________________.

Explanation

When leaves are attached on opposite sides, but NOT directly opposite of each other, the leaf arrangement is called alternate. This means that the leaves are positioned in a staggered pattern along the stem, with each leaf emerging at a different height. This arrangement allows each leaf to receive maximum sunlight and reduces shading between leaves.

Submit
8. When 2 leaves are attached at the SAME position on opposite sides of the stem, the leaf arrangement is called ________________________.

Explanation

When 2 leaves are attached at the same position on opposite sides of the stem, the leaf arrangement is called opposite.

Submit
9. Dicots have leaves with_______________veins.

Explanation

Dicots have leaves with branching veins. This means that the veins in the leaves of dicots diverge and branch out in a network-like pattern. This is in contrast to parallel veins, which are found in the leaves of monocots. The branching veins in dicots allow for a more efficient distribution of water, nutrients, and sugars throughout the leaf, as well as providing structural support.

Submit
10. The flat part of the leaf is called the__________________.

Explanation

The correct answer is "blade" because the flat part of a leaf, which is responsible for capturing sunlight and conducting photosynthesis, is commonly referred to as the blade. The blade is the broad, expanded portion of the leaf that is typically green in color and contains the chlorophyll necessary for photosynthesis.

Submit
11. Many plants have leaf blades that are divided into _____________________.

Explanation

Leaf blades of many plants are divided into smaller sections called leaflets. Leaflets are usually attached to a central stalk or petiole, and they are arranged in a way that resembles the structure of a full leaf. This division into leaflets allows the plant to increase its surface area for better absorption of sunlight and exchange of gases. It also helps in reducing water loss through transpiration, as each leaflet can close its stomata independently. This adaptation is commonly found in plants like ferns, palm trees, and compound leaves of certain flowering plants.
