Explanation / Answer
Hi Answer:
Q.1. Complete the following table
Q. 2 How was the evolution of angiosperms transformed the face of planet.?
Answer: The angiosperms are known as the flowering plants. They produce colorful flowers which attract various insects or pollinators which pollinate the various plants and help to produce fruits which are important food source, medicines and other important by products. The presence of angiosperms only causes this evolution and enhance the beauty as well as the production of food for human as well as animals.
Q.3. Describe the life cycle differences in plantsthat are annuals, biennials and perennials?
Answer: The life cycle is the time period which a plant took from its germination to reproduction and to death.
Q.4. Which of the following is true for basal dicots?
Answer: Option E (Both B and C)
The basal dicots are also known as Eudicots and they have mostly tricolpate pollen and the most common example of these basal dicots are water lilly and sassafras.
Eudicots Monocots Example organisms Forget-me-not, Dandelion and maple Orchids, palm trees, grasses, Bananas Support system Types of roots Tap root system, Protostele pattern of roots Fibrous root system, Eustele pattern of roots Transport system Transpiration stream is used to transport the water and ions by the plants. Vascular bundles scattered throughout the stem. Type of transport Tissues Xylem and phloem arranged in strands known as vascular bundles. The vascular tissue in roots is star shape having phloem between the xylem. Where as stem have ring shaped vascular bundles. Xylem and phloem are present for the transport of water and food. In roots the vascular tissues are in ring shaped and in stem bundles are scattered. Type and arrangement of leaves Dorsiventral, Simple and compound leaves having alternate, opposite and whorled type of arrangement on stem. Isobilateral leaves having parallel venation. Reproduction Sexual reproduction Sexual (seeds) as well as asexual (clonal propagation) Type and arrangement of Flowers The flower arrangement is usually come in the multiple of 4 or 5. The flower arrangement is usually come in the multiple of 3. Types of seeds Seeds are mature ovules having embryo and nutritive tissue for developingseedling. Seeds have two cotyledons’. One cotyledon.Related Questions
