A loculicidal capsule with endospermic seeds.

Cestrum nocturnum of family Solanaceae and Lupinus of family FABACEAE.

Grain legumes are cultivated for their seeds, and are also called pulses. The seeds are used for human and animal consumption or for the production of oils for industrial uses. Grain legumes include both herbaceous plants like beans, lentils, lupins, peas and peanuts, and trees such as carob, mesquite and tamarind. Groundnut and soyabean

The presence of nodulated roots.

Mango and coconut are drupe fruits. They develop from monocarpellary superior ovaries and are one seeded. It is differentiated into outer thin epicarp, middle fleshy mesocarp and inner stony endocarp.
 

The edible part of coconut (Cocos nucifera) is endosperm. The milk of tender coconut represents the oily endosperm in liquid form. Later it gets deposited along the walls of endocarp and forms edible flesh.

Differentiate between pedical and peduncle are

Modified stem bulb is highly reduced disc-like stem.It bears fibrous adventitious roots at its base.Leaf bases form bultslets that grow into new plant,e,g.,Allium cepa(onion).

Differentiate between reticulate venation and paralleel venation are

Testa is the outer hard layer of the seed coat, while tegmen is an nner thin layer of seed coat.

Primary function of the roots is to absorb water and dissolved minerals from the soil. This is crucial as it helps in the process of photosynthesis. Storage: Plants prepare food and store in the form of starch in the leaves, shoots and roots.

Tap roots of some plants become fleshy due to storage of reserve food. The main root stores extra food whereas secondary roots are thin and are involved in absorption of minerals from the soil. The swollen roots occur in different shapes.

The number of leaves arise from a single node in Alstonia, so it is called whorled.

The root bears unicellular root hairs in the zone of maturation.

Differentiate between bract and bractole are

Differentiate between recemose inflorescene and cymose inflorescene are

(ii)  Differentiate between apocarpous and syncarpous ovary is

The inflorescence is how the flowers are arranged on the flowering axis. During the flowering season, the vegetative apex of the stem gets converted into a floral meristem. Based on whether the floral axis continues to grow or ends in a flower, the inflorescence is classified into racemose and cymose. In racemose inflorescence, the floral axis continues to grow and produces flowers laterally. On the other hand, in a cymose inflorescence, the main axis terminates into a flower. Hence, it is limited in growth.
Growth : Indefinite (race mose) and definite.
Number of branches : Cymose, uniparous, biparous, multiparous
Pedicel : Presence or absence of pedicel in inflorescene.
Branching of peduncle : Unbranched and branched.
Sex of flowers : Certain types have unisexual flowers. e.g, Catkin.

Differentiate between fibrous root and adventitious roots are

In insectivorous plant e.g., Nepenthes, the leaf lamina gets modified in the form of pitcher and anterior part of petiole coils like tendril which keeps the pitcher in a vertical direction. Posterior part of the petiole remains flattened like a leaf. The apex of lamina forms a lid. Pitcher contains digestive enzyme which the trapped insects .
All these modifications and adaptation are developed to make up the nitrogen deficiency in the plant because these plants are found in N2 deficient soil, (marshy/swamp soils)

The mode of arrangement of leaves on the stem and its branches is called phyllotaxy (Phyllon-leaf; taxis arrangement). They are arranged most systematically, regularly and mathematically, so as to get proper sunlight and avoid overcrowding.
Phyllotaxy in leaves is of following three types.
(i) Alternate: A single leaf arises at a node. e.g, China rose, mango, mustard, sunflower, etc.
(ii) Oppposite: Two leaves arise at a node,opposite to each other e.g, guava, Calotropis tulsi, etc.
(iii) Whorled: More than two leaves arise at each node forming a circle or whorl, e.g, Alstonia Scholaris etc.

These can be distinguished as follows

Primarily, there are two types of root systems found in plants, namely the tap root system and fibrous root system. The main function of the roots is to absorb water and minerals from the soil. However, roots are also modified to perform various other functions. The roots of some plants act as storage sites for food, some provide support to massive plant structures, while others absorb oxygen from the atmosphere.
Roots and its modifications in various plants:
(a) Banyan tree
The banyan tree (Ficus benghalensis) has massive pillar-like adventitious roots arising from the aerial part of the stem. These roots grow towards the ground and provide support to the tree. Such roots are called prop roots.
(b) Turnip
The roots of turnip (Brassica rape) help in the storage of food. Similar food-storing roots are found in radishes, carrots, and sweet potatoes.
(c) Mangrove tree
The roots of mangrove plants grow vertically upwards from the soil for the absorption of oxygen from the atmosphere as the soil is poorly aerated. These types of roots are called pneumatophores.
